Metrics shows volume out of sync even for deleted replication object.

[winkrs]

Describe the bug

When a replication object with volume out of sync gets deleted, the metrics still show that this object is still out of sync.

Steps to reproduce

Create a replicationSource with the wrong destination address for the metric volsync_volume_out_of_sync is equal to 1. Now delete the replicationSource object and check the metrics again.

Expected behavior

Expected the metrics gauge value to be 0 when the object is deleted.

Actual results

the metrics stay as 1 even when the replication object gets deleted

Additional context

As per my understanding, the gauge metric should be reverted to 0 when the replication object gets deleted. Showing that there is a volume out of sync for a delete replication object creates confusion.
