[Cinder] Enable standard_hdd backend
[Cinder] Enable standard_hdd backend

This patch enables the low performance cinder backend named
'standard_hdd' everywhere.  We still have several regions
that have storage profiles that don't have datastores, due to
a bug in vmware.  Once the cinder-standard-hdd profile is fixed in
those regions, then the driver will report space available for
provisioning.  While the storage profile doesn't have datastores, the
cinder driver will simply report have 0 bytes available for
provisioning and the cinder scheduler will never pick that backend
for a new volume.
