Cutover Migration is stuck at transfer-pvc phase

Description of problem: 

Migrating an app in MTRHO is stuck on the transfer-pvc-0 stage, the last successful log printed is “Generating new certificate” then it fails/ gets stuck.

So far, two different behaviors were observed after that log was printed. One of them is rsync pod getting stuck on not ready status

The second one is an error showing that the certificate secret already exists.

Therefore, it is believed that those issues are related to the generation of the certificate, and/or the certificate secret

Version-Release number of selected component (if applicable):

Source GCP 3.11

How reproducible:

Steps to Reproduce:

2. Import the app in a namespace in the target cluster.

Actual results:
