Use Deployment with leader election instead of StatefulSet

Browse Source 
Deployment behaves better when a node gets disconnected from the rest of
the cluster - new provisioner leader is elected in ~15 seconds, while
it may take up to 5 minutes for StatefulSet to start a new replica.

Refer: 52d1fbcf9d

Fixes: #335
