Created attachment 692720 [details]

Description of problem:

I had some tasks that became zombies and I moved my host to a different DC. 
the tasks, although zombie, could not be cleaned until I reconnected the pool about a week later. 

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


how reproducible:

Steps to Reproduce:
1. run several live storage migration tasks and restart vdsm 
2. put host in maintenance
3. create a new pool with the same host
4. wait for the tasks to become zombie tasks

Actual results:

engine fails to clean the zombie tasks if we cannot find master domain

Expected results:

we should be able to clean the tasks from the db since the tasks are already zombie tasks.

The problem is that when we reach a zombi state, we should not depend on whether there is an active SPM for clearing this task because:

- it should be cleaned ... too old
- in case no spm exist .. those tasks will not appear in it's task list there 
  for no cancel task API will be used.

I had zombie tasks and they were cleaned after 50 hours even after  I changed the DC. 
no errors in the engine log.
