Bugfix: Account for consumed space better 

When the volume service starts up, it goes through all
volumes for a host in the db and adds up the volume size as
a mechanism to account for that allocate space against the
backend.  The problem was that the volume manager was only
counting volumes with a state of 'in-use' or 'available'.
If a volume has a host set on it, then we account for it's
allocated space.

This patch adds other volume states to use to account for
allocated space at volume service startup.

`Bug #1910767 <https://bugs.launchpad.net/cinder/+bug/1910767>`_: Fixed
the calculation of the allocated capacity for the volume manager.
The fix takes into account all volumes that have a host setting, not just
volumes with a status of 'in-use' or 'available'.
