Description of problem: After adding two trailing slash to the exposed registry route, the migcluster resource is showing the status as connected, when we create a migplan from backend with DIM, the plans goes to the unready status.


Version-Release number of selected component (if applicable):
Source GCP 4.6   MTC 1.7.2 + OADP 1.0.3
Target  GCP  4.11   MTC 1.7.2 + OADP 1.0.3


How reproducible: 
Always


Steps to Reproduce:
1. Add two trailing slash (“//”) at the Exposed route host to image registry 
2. Create a migplan, select DIM.


Actual results: Migplan goes to the unready status due to the invalid exposedRegistryRoute.
