Mock the required status fields to persitent and successfully create a route in testenv

The following discussion from !39 (merged) should be addressed:

• @rvineetr started a discussion:

  Route is supposed to be created, but since the 'ReadyReplicas' status in deployment can't be made persistent with the reconcile loop, route won't be created

• Following on this, add a test case to check the domainName implementation being reflected on the route (Follow up from !40 (merged))
