Timeout for readiness probe is too short

[kwk]

The current time for a pod to come up is 30 seconds (thanks to @alexeykazakov for pointing that out too me).

failureThreshold: 3

We want to do a big migration that takes too long to be done in 30 seconds apparently.

Doubling the timeout from 30 to 60 seconds still didn't solve the issue. See this deployment: https://console.rh-idev.openshift.com/console/project/dsaas-preview/browse/rc/core-1261?tab=logs

Doubling the timeout from 60 to 120 seconds still didn't solve the issue (#2295)
