Make ansible-galaxy work as expected

This change fixes hg galaxy roles
Roles also get installed if roles path is missing, which
the tests currently require (fixes #8950)
Allow github style ssh repo names
Don't throw away useful stdout and stderr. Fixes #8418

When supplying a sudo password to a server that uses passwordless sudo,
we should not throw away useful stdout and stderr. This is particularly
important for modules that perform md5 checks as part of the pre module
execution.
Applied fix for sudo with no prompt to paramiko

Effectively reproduces @sivel's work from #8900 but for
the paramiko connection. Fixes #8418 when using paramiko

This allows `_remote_md5` to work if a sudo password is
passed in when no sudo password is required.
[#9048] convert Route53 TTL to integer before comparison

boto/Route53 are returning TTL as a string.
The route53 module is comparing it with an integer and therfore thinks the DNS entry has always changed.
Update rax root pubkey example

The example was showing how to use the `files` option to pass in a local file as an authorized public key for root. While this works, it's a bit sloppy, given that there's a specific option, `key_name` which will use one of your public keys on your rackspace account and add it as an authorized key for root. In our case, one of our admins didn't notice the `key_name` option because they scrolled straight to the example and saw the `files` strategy.

I propose that the example still shows `files`, but not using a root public key as an example, and instead also demonstrate the `key_name` option so that it's clear from the example how to get the initial root public key deployed.
