Tune rally gate jobs for senlin

Two changes are made in this patch:
 - renaming "gate-rally-dsvm-senlin" job to
   "gate-rally-dsvm-senlin-senlin" to let it match the job
   template "gate-rally-dsvm-senlin-{name}" rather than
   "gate-rally-dsvm-{name}".
 - Enabling neutron support for rally gate jobs for senlin.
