Fixes #8324
Improves #7667

rds_module: Fix AWS connection

Remove galaxy CLI tests that hit bitbucket as bitbucket is hanging tests - maybe replace with nice github examples later :)

Conflicts:
	lib/ansible/utils/__init__.py

Also fixes a bug whereby any changes to the route_tables were not
properly reflected by setting changed=True.

Fixes #8666

Avoid multiple blank lines with --syntax-check

Fixed typos

Corrected a simple syntax error in galaxy

Fixes #8681

  Only print a blank line between plays when also doing --list-hosts and/or
  --list-tasks, otherwise this output just a long list of blank lines, one for
  each play.

Ensure that the automated scm determination for github.com
repos still copes with .tar.gz archive files.

Handling .zip archives is left as an exercise for the interested reader

Fixes #8604

Fixed role name for
    - { role: 'lives/in/a/subdirectory' }
Should be 'lives/in/a/subdirectory', not just 'subdirectory'

`ansible-galaxy init --offline ...` can create a role without
talking to the galaxy api server
`ansible-galaxy install ...` only needs to talk to the galaxy api
server for galaxy roles, not tar files or scm archives
Fixed a bug in command line role installation

Older git archive commands create tar archives even with a tar.gz
extension. So change it to always create tar archives and have
the install_role method cope.

Removed ssh roles from the test case as they don't work unless
you can connect to bitbucket via ssh and have your key there.

Corrected a minor typo in error messages

Added docs
Added more tests
Improved how roles are returned from the parsers

* Roles can now be given a friendly name as third field in role spec csv
* Roles can be installed from URL (not just from archived SCMs)
* Integration tests to demonstrate this
* Unit tests to ensure that role spec parsing works as expected

Moved repo_url_to_role_name to common method in ansible.utils
Added unit test for repo_url_to_role_name
Added integration tests for galaxy

Ensure that if meta/main.yml has dependencies containing URLs
these are correctly resolved at playbook runtime.

Update role_name during run time so that output of e.g. task names
look sensible

Change SCM determination from executing git/hg commands to explicit
in URL.

Fix check for already installed dependencies

ansible-galaxy can now refer to SCM URLs (git and hg at this point)
for role names
Dependencies need to use the full SCM URLs too.
Otherwise all seems to work well

(works with ssh too)
