Glance is breaking the swift client gate

[Stuart McLaren]

    Need to correct how swift_store_endpoint is defaulted.

    Currently:

    swift_store_endpoint = None

    will initialize it as a string, which would cause a 'ClientException:
    Unsupported scheme' exception to be raised by head-of-tree swiftclient.

    This was breaking the swiftclient gate (gate-tempest-dsvm-neutron-src-python-swiftclient).
