Issue:
Fix lint and mypy with Python < 3.8
In https://github.com/certbot/certbot/pull/8748, we made a change that causes our lint and mypy tests to need to be run on Python 3.8+ to pass. See https://github.com/certbot/certbot/pull/8748#issuecomment-808790093 for the discussion of the problem here.

I don't think we should do this. Certbot supports Python 3.6+ and I think it could cause a particularly bad experience for new devs that don't happen to know they need Python 3.8+. This change also broke our development Dockerfile as can be seen at https://dev.azure.com/certbot/certbot/_build/results?buildId=3742&view=logs&j=bea2d267-f41e-5b33-7b51-a88065a8cbb0&t=0dc90756-6888-5ee6-5a6a-5855e6b9ae76&l=1873. Instead, I think we should change our approach here so the tests work on all versions of Python we support. I'm open to other ideas, but the two ideas I had for this are:

1. Just declare a runtime dependency on `typing-extensions`.
2. Add `typing-extensions` as a dev/test dependency and try to import it, but use similar fallback code to what we current have if it's not available.

What do you think @adferrand? Are you interested in working on this?

Issue:
ANSI sequences (colors, bold) don't render properly on Windows
## My operating system is (include version):
Windows Server 2019

## I installed Certbot with (snap, OS package manager, pip, certbot-auto, etc):
1.15.0 installer

## I ran this command and it produced this output:
![image](https://user-images.githubusercontent.com/311534/118091733-82af4b00-b40e-11eb-862c-a5848683bc3b.png)


## Certbot's behavior differed from what I expected because:
We should get the terminal to render ANSI properly or not print those sequences at all.

Issue:
Warn user for broken webserver configurations when deleting a certificate (after revoking)
Currently, when the user revokes a cert, it gets the following question:

https://github.com/certbot/certbot/blob/8759ccaecb69ea93c5b3c95f6af71bb9130117b1/certbot/certbot/_internal/main.py#L597-L602

Today, someone on the Community was left with a "catch 22" (broken webserver getting in the way of getting a new certificate): https://community.letsencrypt.org/t/had-to-revoke-some-certs-now-im-stuck/148574

I'm not sure what the generic cert delete command gives as a warning, but I would like to propose **adding a warning to every certificate deletion action in certbot** that it might leave your webserver configuration broken!

We've seen this quite often on the Community and not many users are aware of this fact.. Especially as certbot can perfectly do the HTTP to HTTPS transition, but is NOT able to transition back again from HTTPS to HTTP.


Discussion:
See also https://github.com/certbot/certbot/issues/6734.
There are additional ideas for how to deal with this problem at https://community.letsencrypt.org/t/certbots-cert-revocation-needs-an-update/148588.
I intend to tackle this soon. 

My plan is to extend the apache+nginx authenticators to detect if the lineage being deleted is in-use, and to stop (warn) the user with a list of the relevant vhost files.

Issue:
How to handle dependency on dnspython >= 2.0 for RHEL/CentOS
Since commit 295dc5a2 (#8990) the plugin uses dnspython's `is_address()` helper function which was added in dnspython 2.0 ([commit 037dfe7f](https://github.com/rthalley/dnspython/commit/037dfe7f71f21e37fade0e3a203e38b675a1aa43)).

Actually this change is just a quick fix to get the correct dependencies. Actually the problem for CentOS is that RHEL 8 ships python3-dns 1.15.0-10.el8 in base which means upgrading that dependency is close to impossible. To continue shipping the latest versions of certbot to RHEL/CentOS users I need to come up with a workaround.

Ideas:

- Add a copy of `is_address()` to certbot's rfc2139 plugin (as compat fallback only)
- If dnspython is too old and `is_address()`  is not available, just skip validation (same behavior as certbot 1.18)
- downstream patch for RHEL only (I'd like to avoid that if possible!)

cc @osirisinferi, @alexzorin as you were involved in the original pull request.


Discussion:
Thanks Felix. My bad for not noticing that function not present in our oldest dependencies.

>Add a copy of is_address() to certbot's rfc2139 plugin (as compat fallback only)

An unrelated PR [recently added this function to `certbot`](https://github.com/certbot/certbot/blob/bd5f4f2d8ac3ad9e5afecab28d4806c538b1dc4d/certbot/certbot/util.py#L567-L587), so I think we can go with this option.

Issue:
windows: webroot web.config can cause an HTTP 500 due to duplicate mimeMap
The feature we added in #9054 [is causing problems](https://community.letsencrypt.org/t/certbot-1-21-webroot-http-500-1-20-works/164870/6?u=_az).

If there is another `web.config` file, higher in the webroot directory tree than `acme-challenge/`, which also defines a `mimeMap` for extensionless files, then IIS will crash on  the duplicate `mimeMap` as it merges the configs.

I think this probably a likely scenario for our Windows users to encounter, because I recall seeing (and have posted myself) advice to create `web.config` files in the `.well-known` directory rather than the `acme-challenge` directory.

Rather than traversing the filesystem looking for other `web.config` files, one way to fix this could be to use the `remove` element to remove any existing `mimeMap` for extensionless files, before we add ours:

```xml
      <staticContent>
	  <remove fileExtension="."/>
          <mimeMap fileExtension="." mimeType="text/plain" />
      </staticContent>
```

That seems to work on Windows Server 2019.

One thing that makes me nervous is that `remove` is conspicuously missing from the documentation for `mimeMap` and `staticContent`. I'm guessing it's some kind of generic element and I'm looking in the wrong place. I found the solution on some random blog.

Issue:
snap_config.prepare_env can hang forever if snapd is malfunctioning
Reported at https://community.letsencrypt.org/t/sudo-certbot-renew-hangs-forever/138649

There's some evidence in that thread that `snapd` can get into a state where it just stops responding to commands (whether via `snap`, `snapctl`, or the REST API directly).

Certbot should guard against the possibility of hanging forever, by setting timeouts on relevant network operations:

https://github.com/certbot/certbot/blob/9ca7f76505b10b2f395ddffc4ddc1cbc8afb516b/certbot/certbot/_internal/snap_config.py#L87-L89

Edit: to clarify, although the reported issue involves the previous shell-based snap wrapper, I have reproduced the same hang and lack of effective timeout with the current Python implementation.

Issue:
When ACME meta field is absent, Certbot asks user to agree to "None" terms of service
In #8976 we discovered that Certbot sometimes asks you to agree to a non-existent ACME Terms of Service:

    Saving debug log to /var/log/letsencrypt/letsencrypt.log

    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    Please read the Terms of Service at None. You must agree in order to register
    with the ACME server. Do you agree?
    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    (Y)es/(N)o: n

This can be reproduced when the ACME server is missing a `meta` field, such as in the case of Step CA where the ACME directory looks like:

```json
{"newNonce":"https://localhost:8443/acme/acme/new-nonce","newAccount":"https://localhost:8443/acme/acme/new-account","newOrder":"https://localhost:8443/acme/acme/new-order","revokeCert":"https://localhost:8443/acme/acme/revoke-cert","keyChange":"https://localhost:8443/acme/acme/key-change"}
```

In Certbot, the ToS callback has this guard around it:

https://github.com/certbot/certbot/blob/3058b6e748d085f53dd5c550be2806b26e7195eb/acme/acme/client.py#L865-L867

However, in conjunction with the ACME directory above, the guard is ineffective:

    client_v2.directory.meta=Meta(terms_of_service=None, _terms_of_service_v2=None, website=None, caa_identities=None, external_account_required=None)

We need to check that `terms_of_service` itself is not empty.

Test patch:
Repository: certbot/certbot

Issue:
Log files in /tmp do not have "certbot" or similar in filename
## My operating system is (include version):

Debian 4.19.181-1 (2021-03-19) x86_64 GNU/Linux

## I installed Certbot with (snap, OS package manager, pip, certbot-auto, etc):

OS package manager (apt)

## I ran this command and it produced this output:

N/A

## Certbot's behavior differed from what I expected because:

Certbot created approximately 264,744 log files in `/tmp/` from failing to get a lock (I think this is due to the specific way I run certbot in a cronjob). I asked in #9173 and was told this was expected behaviour, and I should delete them if I don't want them. However, since the files are simply named `/tmp/tmpXXXXXXXX` (where the Xs are random characters), it's impossible to delete just the certbot crash logs just by name — I need to either blow up every file starting with `/tmp/tmp*`, or write a script to grep for some specific string.

Instead, they should be named something like `/tmp/certbot_error_XXXXXXXX`.

## Here is a Certbot log showing the issue (if available):

N/A

## Here is the relevant nginx server block or Apache virtualhost for the domain I am configuring:

N/A


Discussion:
If there's a way to do this safely with minimal changes to our code, I'd accept a PR for this.
