Adding host motd files
Adding crick:/scratch to nfs in workstation role

Updated formatting of MOTD
Removing vagrant temp file dir from index
Removing jp/mallar/david local user creation

It doesn't work. The ansible command insists on creating a local user even
when the only thing specified is group membership. Since users come from NFS,
we don't really want to actually create a local user in /etc/passwd.

Perhaps we can do this with the 'command' module.
Cleaned up inventory
Removed cinnamon desktop

ppa is no longer being updated. We'll add this back in when we figure
out what the new, proper way to get cinnamon is. Luckily, no one is using
it.
Reduced /home timeouts and mount options.

Based on my reading online, these settings may improve process 'freezing' because
the mounts will expire more quickly. As well, because they are soft mounted and interruptable
this should make for a more graceful degradation if the server fails.

Of course, with soft mounting there is some chance of data lost, but this
shouldn't be too much of a problem hopefully.
Added space usage cronjob to servers
