OpStatusToPDPB converts OpStatus to pdpb.OperatorStatus.
OpStatusToString converts Status to string.
ParseOperatorKind converts string (flag name list concat by ',') to OpKind.
SkipOriginJointStateCheck lets the builder skip the joint state check for origin peers.
SkipPlacementRulesCheck lets the builder skip the placement rules check for origin and target peers.
