Jean-Philippe Evrard 12a3fbafd0 Fixing keepalived bug when 2+ backup nodes have the same priority
The issue is present if you're running 2 or more nodes with
a keepalived < 1.2.8. This bumps the version of keepalived role
(installing a more recent version of keepalived by default) AND
edits the keepalived configuration file to avoid having nodes
with the same priority.

This will restart your keepalived service.

Please note this commit is not meant for backporting. The deployer
running on mitaka and below should follow the documentation here:
