all remaining kube-managers died after a HA failover

[Vedamurthy Joshi]

R4.0.1.0 Continuous build 24 Ubuntu 16.04.2 with fixes for bug 1710744 and bug 1711274

nodec1/nodec2/nodec3 are the 3 controller nodes which also have kube-manager containers

On nodec3, all containers were stopped around 11:02:53 AM

docker stop contrail-kube-manager ; docker stop analytics ; docker stop analyticsdb ; docker stop controller

It was seen that the other two kube-managers died at that time.
Surprisingly, no tracebacks/errors are seen during this period

Logs will be in http://10.204.216.50/Docs/bugs/#

Restarting one of the kube-managers brought them up fine and zk election happened properly as well

Fixed ha fail over issue for kube-managers

The restart policy should be 'always' in the
contrail-kube-manager.service. so that if
there is an exception happens in the zoo-keeper
client, systemd would take care of it
