Dustin 2f9d8ad618 jenkins: Add CA key to ssh_known_hosts 
Since (almost) all managed hosts have SSH certificates signed by SSHCA
now, the need to maintain a pseudo-dynamic SSH key list is winding down.
If we include the SSH CA key in the global known hosts file, and
explicitly list the couple of hosts that do not have a certificate, we
can let Ansible use that instead of fetching the host keys on each run.
