Add "RepositoryStatusMessage" and detailed information about initilization

Summary:
`RepositoryStatusMessage` is basically a key/value table associated with a repository that I'm using to let the daemons store the most recent event of a given type, so we can easily show it on the status dashboard. I think this will be a lot easier for users to figure out than digging through logfiles.

I'm also going to write the "this needs a pull" status here eventually, for reducing the time lapse between pushes and discovery.

  - Add storage for these messages.
  - Have the pull engine populate the INIT phase. I'll do the FETCH phase next.
  - Update the status readout to show all the various states.

Test Plan: See screenshots.

Allow null for token expiration date

Summary: At least under GitHub, the token value is stored as "null", and not missing. And `null > anything` is false, so Phabricator thinks the token is expired or not there.

Test Plan: http://ph.vm/settings/panel/external/ before shows "No OAuth Access Token," and after it says "Active OAuth Token".

Preserve linebreaks again in Summary / Test Plan for revisions

Summary:
I pulled these into the property list recently, which made them more consistent, but that dropped "preserve linebreaks". Since these usually come from the CLI, render with linebreaks preserved.

@csilvers, you'll need to `bin/cache purge --purge-remarkup` after this if you want to fix existing revisions.

Test Plan: Made a revision with some poetry, saw poetry preserved.

Show additional status information during repository import

Summary:
Ref T2350. Fixes T2231.

  - Adds log flags around discovery.
  - Adds message flags for "needs update". This is basically an out-of-band hint to the daemons that a repository should be pulled sooner than normal. We set the flag when users push a revision, and expose a Conduit method that `arc land` will be able to use.

Test Plan: See screenshots.

Implement writes over HTTP for Git.

Summary: Depends on D7642.  This updates the authentication logic so that HTTP writes can be made to Git repositories hosted by Phabricator.

Test Plan: Set the policy to allow me to push and I was able to.  Changed the policy to disallow push and I was no longer able to push.

Mark IMPORTED_CHANGE more consistently

Summary:
See <https://github.com/facebook/phabricator/issues/425>. There are some ways that the change parsers may not reach `finishParse()`, but we now need them to in order to mark the commit imported, advance the progress bar, and eventually kick the repository out of IMPORTING status.

Take all the copy/pasted code in the parsers and move it into the parent. Specifically, this is:

  - Printing a status message about starting a parse;
  - checking for bad commits;
  - queueing the next parse stage; and
  - marking the import step complete.

Test Plan: Used `reparse.php --change` to reparse Git, SVN and Mercurial repos.

Improve repository hinting and feedback

Summary:
  - Warn about "Read/Write" instead of disabling it, to prevent edits which mutate it after changing a hosted repository to an unhosted one.
  - Warn about authenticated connections with HTTPS auth disabled, and link to the relevant setting.
  - When "Autoclose" is disabled, show that "Autoclose Branches" won't have an effect.
  - For hosted repositories, show the HTTP and SSH clone URIs.
    - Make them easy to copy/paste.
    - Link to credential management.
    - Show if they're read-only.
    - This could be a bit nicer-looking than it is.

Test Plan: Looked at repositories in a bunch of states and made various edits to them.

Survive pull/discover for hosted repositories in all VCSes

Summary:
Hosted repositories only sometimes survive the pull/discover phases right now, due to issues like:

  - Pull tries to `git clone`, but should `git init`.
  - Mercurial doesn't handle empty repositories with on branches.
  - SVN tries to connect to an invalid remote.
  - None of them set the INIT repo flag correctly, so status doesn't get updated properly in the UI.

Fix all this stuff.

Test Plan:
  - For each of Git, SVN and Mercurial:
    - Created a new repository from the web UI in a deactivated state.
    - Made it hosted.
    - Manually ran pull/discover.
    - Verified we end up with initialized, empty repositories in consistent states.

When creating a repository in Diffusion, prompt for "Create" or "Import" first

Summary:
Ref T2230. This will need some more refinement, but basically it adds a "Create" vs "Import" step before we go through the paged workflow.

  - If you choose "Create", we skip the remote URI / auth stuff, and then set the "hosted" flag.
  - If you choose "Import", we do what we do now.

Test Plan: Created and imported repos.
