Bug Description

When HAProxy is configured on multiple hosts, keepalived is used by default.
If running on 2 hosts, the issue won't appear.

When running on 3 hosts or more, with the current configuration, 2 of them will be considered as slaves, and will have the same priority.

This poses a problem with keepalived 1.2.7 and is fixed in the next version of keepalived.

    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:
