[Takashi Kajinami]

Description
===========
The exceptions in glanceclient.exc were deprecated in glanceclient 0.4.0[1].
 glanceclient.exc.Forbidden
 glanceclient.exc.NotFound
 glanceclient.exc.ServiceUnavailable
 glanceclient.exc.Unauthorized

But these are still used in the code.

We should replace these by the new HTTP* exceptions.
