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.
