Fix for snapshot-controller failure during restore
The change made in review [1] introduced the creation of the snapshot resources in all installations during the bootstrap. An issue was identified during the restore process (uses bootstrap playbook) in a specific scenario: systems with more than one host where the volume snapshot controller pod was not running on controller-0 when the backup was performed. During the restore process, within the snapshot-controller role, it checks if the snapshot-controller pod is running, resulting in a failure in the above scenario, since the assigned node will not be ready, as only controller-0 is ready to run pods during restore. Therefore, the fix involves skipping the execution of the role during restore. It's important to note that if the snapshot-controller pod was created before the backup, it will later be restored and will operate correctly after completing the restore process regardless of the node that was attached.
