Description of problem:

Action: using vdsClient, try to disconnectStoragePool 
Result: Cannot activate Logical Volumes: ('General Storage Exception: (\'5 [] [\\\'  Volume group "91f4fea6-8cc6-4425-8cd7-247bf0dac703" not found\\\', \\\'  Skipping volume group 91f4fea6-8cc6-4425-8cd7-247bf0dac703\\\']\\n91f4fea6-8cc6-4425-8cd7-247bf0dac703/[\\\'metadata\\\']\',)',)

Scenario: 

- createStoragePool (SAN)
- connectSoragePool
- brutally, remove all storage domains:
  cmd: gremove `vgs --noheadings | awk '!/vg0/{print $1}'` --force
- using vdsClient, disconenctStoragePool

vdsClient 0 disconnectStoragePool  `vdsClient 0 getConnectedStoragePoolsList` 1 `vdsClient 0 getConnectedStoragePoolsList`

Notes:

- we had some work around this scenario in the past, and it used to work, from some reason, code has changed to read master domain metadata - we don't need that.
