The PR disables mirroring on a pool when PoolSpec.Mirroring.Enabled is set to false - disable mirroring on the pool for `Mirroring.Mode == pool` - Add warning for the user to disable mirroring manually for `Mirroring.Mode == image` - Stop the mirroring health checker goroutine - Reset the mirroring health check status in the CR.
