Allow 'description' in V3 Regions to be optional

Currently, description is required for POST requests to regions when
using the SQL backend. According to the Identity V3 API spec,
description is not required. If a user creates a region without
specifying a description for the region in the request, we can make sure
it is sent to the database as an empty string.
