SolrCloud readiness blocking waiter

SolrCloud doesent expose node readiness condition in status, which can be used by wait/jobs.
This utility blocks until requested cluster is ready. We compare replicas with readyReplicas in status of SolrCloud resource.

If there is an easier way to do this (e.g. with some kubectl wait --for=condition=[magic] command) please let me know.
