ssh_host_keys
We are now distributing an ssh_known_hosts file to all of our servers.
This means that you can blow away your ~/.ssh/known_hosts file. When
servers get rebuilt either replace it with the old ssh key, or update the
puppet/modules/ssh/files/ssh_known_hosts file with the new key.
I've not actually used global ssh_known_hosts before, I wouldn't be
surprised if it causes issues in some of our scripts that might have a
conflicting ~/.ssh/known_hosts. Lets keep our eyes open.
