DT Merge.

This is the guts of the DT merge. 

Multiple NTP servers: https://bugs.launchpad.net/openstack-cisco/+bug/1159595
Interface templating: https://bugs.launchpad.net/openstack-cisco/+bug/1159597
All config accessible from site.pp : https://bugs.launchpad.net/openstack-cisco/+bug/1159598
Move cobbler node define out of site.pp: https://bugs.launchpad.net/openstack-cisco/+bug/1159602

Additional testing is needed, but the puppet runs and node deployment all seem fine.
