[nagadeesh-nagaraja]

when server is missing and servermaintenance is deleted, its stuck because it tries to fetch the server object and keeps failing.

2. Try to delete the ServerMaintenance and Observe controller behavior
3. See error, that its not being deleted
4. try to delete the finalizer and try to force delete, still observe that the obj is not deleted
