Creates a VMware vSwitch
We have an end-to-end playbook that performs bare metal provisioning and
configuration of vSphere.
The playbooks/tasks and results from that testing is what will be listed
in this PR.
If there are any questions please let either @jcpowermac or @mtnbikenc
know.
Tested with version
```
$ ansible-playbook --version

Right now even if you pass in an empty tags list to the module (either with
an empty string or null) it will erroneously think the tags list have changed
and re-apply the tags on every run
pkgin searches for packages such as 'emacs' can return multiple matches,
the first of which is not guaranteed to match. So, iterate through
found packages until we have an appropriate match. Should we *not* find
a match, then return False indicating match failure.
