Add OpenSUSE network settings
Highly limited osx (darwin) guest plugin.

- Tested on mountainlion/virtualbox
- virtualbox shared folders will not work (no vboxvsf support)
- Must use at least 2GB of RAM or the os will refuse to boot(mountainlion requirement)

To begin, create a mountainlion vm in virtualbox. You will need to install from scratch most likely, and assign at least 2GB of ram for it to install.

Create 2 network interfaces, the first one a NAT interface, second a hostonly interface.

'vagrant package' the VM.

In your vagrant file, be sure that the synced folder is disabled:
config.vm.synced_folder "vagrant", "/vagrant", disabled: true
Add a post plugin install message to en.yml
Display post install messages if a plugin has any
Fix Ansible provisioner exit code reporting

In eb70c0d6bbc8 we were trying to compare a Subprocess::Result to a
Fixnum, resulting in Vagrant always reporting failure regardless of
Ansible's exit code.
Update host.rb

Vagrant has been failing to run on CentOS 6 since version 1.2.5.
The read of file /etc/redhat-release appeared to be only checking for the word Fedora. Altered the regex to match CentOS as well
Working implementation with NFS, still some caveats:
- There's a lengthy sleep in there, probably could use a back-off loop
- en1 seems totally worthless on vbox, I skip it and just use the en2 it creates.
Added :owner => root to mount options
Use longest machine name to pad in status cmd
Start padding with 25 characters to keep original behavior
Forcing eth0 to come up
Change mount_nfs_folder cap to be more like the linux version, adding a
bunch of retires rather than a long sleep.

Add DarwinNFSMountFailed error. This might move be more appropriate at
the plugin level.

Integrate some of tvsutton's work in configure_networks to get the
implementation closer to working in both fusion and virtualbox.

Add shell_expand_guest_path capability (also copied from linux)
Tabs must die.
Remove the +1 offset, I resolved the issue with the 'phantom' en1
interface. For some reason interfaces still skip en1, but provided we
enumerate based on order and not name, things should work smoothly.
Darwin guest: mount_vmware_shared_folder cap for use with vmware_fusion provider

- It's not clear whether it's possible to mount individual shares
  using 'mount -t vmhgfs', as the vagrant-vmware-fusion provider now does
  for Linux guests. Any mount from '.host', even if not a valid share
  name, succeeds and mounts _all_ shares in their respective directories
  at the root of the mountpoint. Instead, we symlink each directory from
  its place in '/Volumes/VMware Shared Folders'
Darwin: clean up temporary network interface file downloaded from guest
Update Darwin guest description
Darwin: code debug cleanup
Darwin: use :sudo for communicate.test
Ansible inventory can be a directory, not just a file

It is an under-documented feature that one can specify a directory as
the Ansible inventory source, not just a single file. In that case,
Ansible merges the contents of flat files and any executable inventory
plugins found in the directory.

This is useful, for instance, to put localhost in your inventory for use
with `local_action` even if your entire infrastructure is otherwise on
EC2 or some other dynamic inventory source. I also use a flat file to
create aliases for host groups automatically generated from the EC2 API,
like "staging" for `tag_Environment_staging`.
