Network interruption during interfaces configuration - solved

First tentative to maintein connection under "if $_external_device" statement

added user grant for cinder, glance, neutron, nova and keyston on mysql cluster temporarily from localhost and haproxy settings for nova and neutron. Cleaned up other haproxy unused (commented)

used keepalived module from puppetforge instead of baltig and changed resource definition in manifest/profile/keepalive.pp

modified database.pp profile, putting percona instead of galera. Ensured xinetd package installed and service started
