Code Issues Proposed changes

Update the liveness probe to verify postgres connectivity

Browse Source 
Change the tillerLivenessProbeTemplate to test the connectivity to the
postgres backend. We will override the periodSeconds and
failureThreshold when installing the helm chart to trigger a restart of
the tiller pod over a swact when the postgres DB/server moves from one
controller to the other.

This will help guarantee that the tiller connection is always
re-established if the connectivity to the postgres backend fails.
