Issue 291: Fixing post-install-upgrade hook

[SrishT]

Signed-off-by: SrishT [email protected]

Change log description

The post-install-upgrade hook in zookeeper cluster charts currently does not verify that all desired replicas have been deployed.

Purpose of the change

Fixes #291

What the code does

The hook compares that the number of ready replicas is equal to the replica count mentioned within the spec, i.e. it checks that .status.readyReplicas == .spec.replicas

How to verify it

The zookeeper cluster deployment should succeed only when all the desired replicas have come to ready state.
