Title:
Glance adding image member fails with multibackend

Fix Released
Bug description:
When adding an image member to a shared image, we get the following
traceback on glance-api:
Traceback (most recent call last):

in get_location_from_uri
raise exceptions.UnknownScheme(scheme=pieces.scheme)
UnknownScheme: Unknown scheme 'file' found in URI
Related config is:
[DEFAULT]
enabled_backends = gpfs:file
[gpfs]
filesystem_store_datadir = /path/to/Openstack/Glance
If I'm reading this right, the issue is related to
glance_store.location.SCHEME_TO_CLS_MAP being empty. This causes
backend.get_location_from_uri to fail to look up the scheme.
I think this is happening because backend.py is populating
location.SCHEME_TO_CLS_MAP, but multi_backend is populating
location.SCHEME_TO_CLS_BACKEND_MAP. Because
location.get_location_from_uri is only looking at SCHEME_TO_CLS_MAP,
when it is called with a multi-backend config, it fails to find any
registered schemes.
