Fix for adopt glance.store library in Glance

[Ankit Agrawal]

The store module is removed from glance project and new glance_store module is created, but the glance project code was not updated properly for the required changes.

There are few cases in v1 api which needs to be addressed:

1. _get_from_store method raises store.NotFound exception from glance_store but it is still trying to catch exception.NotFound exception in glance and the actual exception has not been caught which causes 500 HTTPInternalServerError.

2. _get_size method raises store.NotFound exception from glance_store but it is still trying to catch exception.NotFound exception in glance and the actual exception has not been caught which causes 500 HTTPInternalServerError.
