Fixing bugs

[tanmayja]

1. In case of unavailable partition recovery, scale up the cluster with batch and wait for sts after scale up.
2. In case of security enabled flag:
   • if status.pods is nil, don't allow security update.
   • if isSecurityEnabled(status.aerospikeConfig) is true and spec is false, then don't allow to disable security.
   • make IsSecurityEnabled flag optional
3. In case of multiPodPerHost, deref the value and then compare
4. In case of dynamic config update, if EnableDynamicConfigUpdate flag is true in spec and false in status, check for all the pod's annotation. If any pod does not have config annotation, update the annotation.
