Description of the problem: On creating an intra cluster source to source state-migration migplan, it shows a warning in the migplan for the unavailability of storage class on the destination cluster.

Severity: Medium

Version-Release number of selected component (if applicable):
MTC 1.7.0 
Specific to Glusterfs
Source cluster - OCP 3.11 (Glusterfs installed and set to default)
Target cluster - OCP 4.6+ (Glusterfs not available)

Steps to reproduce:
1. Create a namespace named state-ns in the source cluster
2. Deploy any application in the namespace having PVCs
3. Login to the MTC console, and create a state migration type migplan for the state-ns namespace created in the first step.
4. Click on Next, and Choose the target storage class to gp2 available in the target cluster and Finish the migplan.
5.  Check the created migplan yaml from the backend.

Actual Result: 

  - category: Warn
    lastTransitionTime: "2022-03-10T08:01:42Z"
    message: 'Ceph is not available on destination. If this is desired, please install
      the rook operator. The following PVs will use the default storage class instead:
      [pvc-dc6e5385-a047-11ec-b6a2-0ecd89df8903]'
    status: "True"
    type: PvWarnNoCephAvailable

“PvWarnNoCephAvailable” warning is visible in the migplan


Expected Result: This warning should not be visible as this is an intra cluster state migplan.
