Another case of adding a resource from v3 to the legacy v2 API. We
tackled Extension in change I1e4528f5a5d8e2caaaf204792ddcee7267e4c2e9
and Capability in change I98252ddd0dadba2bfa1aaf97b59932a19c396cd4. Now
it's time for Limit.
Note that the API is unchanged between v2 and v3 so this can be a
straightforward copy-paste job. This was determined by inspecting the
cinder code before the v2 API was removed (e.g. commit 'e05b261af~',
file 'cinder/api/views/limits.py').
