Clone_image should return dict of vol properties, clone status.

The method will work fine in case of drivers not dependent
on volume properties like provider_location. It will fail to
restart in case of nfs drivers and also leave volume created as
result of clone_image functionality created in the
nfs share in dangling state after deletion as provider_location
is None. This fix requires dict of volume properties, cloned status
to be returned which facilitates passing back provider_location
in case of nfs drivers and hence resolves the issue.

Make Storwize/SVC tests work without simulator.

Moved to using brick to get connector info and fixed a small bug to get
tests working on real storage again. Also fixed up simulator to handle
the multihostmap case properly.
