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.
