What is the current behavior?

Problem of unavailability some hosts at the time of cluster creation. Storage/Database object moved to "Ready" status only when all NodeSet provisioned and Ready. We should be able not to wait for all hosts to start and only check the creation and preparing of all necessary objects.

Issue Number: YDBOPS-9613

What is the new behavior?

• Status.state DatabaseNodeSetPreparing and StorageNodeSetPreparing to determine handleResourceSync step first running
• New conditions for NodeSet* objects:
  • NodeSetPreparedCondition to determine that all child resources created
  • NodeSetProvisionedCondition to determine that all pods are created and have status.phase=="Running"
  • NodeSetReadyCondition to determine that all conditions are True and last Reconcile successfully moved to Ready status
  • NodeSetPausedCondition to determine that all conditions are True and last Reconcile successfully moved to Paused status
• Set "Unknown" status for condition and change value of .status.state on step first run
• Set "False" status for condition if non-Kubernetes error inside current Reconcile run
• Set "True" status for condition if non-True status was set previously

Other information

• Move handler for .spec.operatorSync to handleResourcesSync step
