BUG 1238: Fix configmap registry server readiness probe timeouts

Description of the change:

The configmap registry server readiness probe was defaulting to 1 second timeout.
In cases where cluster/node is a bit slow, the pod goes into CrashBackOff.

Increasing the readiness probe initial delay and timeout for the probe itself.
The failureThreshold for readiness is 3, this gives it 15 seconds total to get going.
