Creating multiattach volume is a non-admin operation but creating
multiattach volume type is an admin operation.
Previously cinder allowed creating multiattach volumes without a
volume type but that support is being removed with[1].
The change requires updating tempest tests[2] but some tempest
tests are non-admin, which require admin priviledges to create the
multiattach volume type.
Based on the last discussion with tempest team[3], the proposed
solution is to create a multiattach volume type in devstack,
if ENABLE_VOLUME_MULTIATTACH is True, and use it in tempest
tests. Similar to how admins create multiattach volume types
for non-admin users.
This patch creates a multiattach volume type if
ENABLE_VOLUME_MULTIATTACH is True. Also we set the multiattach
type name as a tempest config option 'volume_type_multiattach'.
