Allow configuring distributed image import

Glance has recently added distributed image import support where
a new parameter 'worker_self_reference_url' has been added by which
other workers will get to know how to contact the worker which has
staged the image.

In this patch, adding configuration of 'worker_self_reference_url'
by providing it the internal API URL for each node where glance api
will run when glance-direct method of image-import is enabled.
