Support multiple Cinder backend types
This is the first step in supporting multiple Cinder backend types at once. It initially converts the existing hard-coded multi-lvm support to a new cinder_backends driver form. Eventually the cinder_plugins will be converted to this form so they can be enabled more than just one at a time using CINDER_ENABLED_BACKENDS. The default configuration should be identical to the previous defaults, including for both True and False values of CINDER_MULTI_LVM_BACKEND. The existing cinder_plugins are expected to be removed when this is complete. They should continue to work until they have been converted. Add wait for c-api to ensure it is started before continuing. Change-Id: I93b8ef32832269d730c76a6dc24ddb4f20c6d9df
