Change /etc/hosts from 127.0.1.1 to static FRONT ip.

Change the /etc/hosts entry from being like:

127.0.1.1       mira006.front.sepia.ceph.com    mira006

to:

10.214.131.130  mira006.front.sepia.ceph.com    mira006

so that lookups to the the machines own hostname resolve to its
front IP address instead of 127.0.1.1.
