I added all known virtualization types from the virt-what project. However, the few virt types that rely on cpuid information have not been implemented lacking native python cpuid access. (hyperv)

Seems a bit strange I have to set a default in two locations.

Fixes #1624.

Some services allow additional arguments to be provided on the command line. This patch makes it possible.

fix

Fix for #1577 (python 2.4 compliance for mysql_user), tested only for syntax, please exercise MySQL fans!

run - lets act on those hosts in the next play

Without this fix, generating documentation results in:

```
Traceback (most recent call last):

The option will be passed to the Popen object created and will be used to
execute the command instead of the default shell.

- Make sure exit_json() always returns a changed= value
- Modify the yum module to not return failed=False
- Modify install() and latest() similar to remove() in yum module
- Changed exit_json(failed=True, **res) into a fail_json(**res)
- Make sure yum rc= value reflects loop (similar to how we fixed remove())

This also adds module as an argument to keyfile().

Rewrote switch_version() to read .git/HEAD to find branch associated
with HEAD.  If in a detached HEAD state, will read
.git/refs/remotes/<remote>/HEAD.

This makes more sense as there is no purpose in running these remotely.

Rename pull() to fetch().  It does a git fetch and then a
git fetch --tags.
Add _run() method to handle all subprocess.Popen calls.  Change
all previous calls to subprocess.Popen to use _run().

fix case in which file is created and backup is requested but fails, not it just doesn't attempt to backup the missing file

There is no need to require thirsty mode when the destination is a directory. We add the basename of the url to the destination directory and proceed with that. If that file exists in non-thirsty mode continue as expected.

I also cleaned up some of the logic that is no longer necessary if we simply rewrite the destination from the very start the way it is expected.

Also fix missing -G on groups change
