Many exceptions have been deprecated since 0.10.0 glance_store release and it's about time to remove them. This commits removes such exceptions from glance_store/exceptions.py file . As there are no tests associated with these exceptions, no tests have been removed. This commit has been tested locally with the glance unit tests on py27, pep8, releasenotes, docs test environments to ensure glance works with it. Change-Id: I24b4f8c56e60d1ff9fc970465fa155d01b349288
