Description of problem:
hosted-engine --vm-status shows information about the engine VM and information about the involved hosts reading from the hosted-engine metadata.
On hyper-converged setups it doesn't show information about the storage status (which is relevant since it's on the same hosts) and it just show a bad exception when the storage, and so the metadada area, is not available according to hosts status.

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


How reproducible:
100%

Steps to Reproduce:
1. deploy hosted-engine in hyper-converged way on three hosts
2. bring down two hosts
3. run hosted-engine --vm-status on the active host

Actual results:
No info about the hosted-engine hyper converged storage is shown.
An error "ovirt_hosted_engine_ha.lib.exceptions.RequestError: Failed to set storage domain FilesystemBackend, options {'dom_type': 'glusterfs', 'sd_uuid': '537b7b03-7ec7-4fd3-bcf5-000d7a5d162f'}: Request failed: <class 'ovirt_hosted_engine_ha.lib.storage_backends.BackendFailureException'>"
is show..

Expected results:
It shows information about the hyper-converged hosted-engine storage.
