To prevent client use v2 patch api to handle file and swift location

The change will be used to restrict client to download and delete any
file in glance-api server. The same resone and logic as what we did in
v1:
https://github.com/openstack/glance/blob/master/glance/api/v1/images.py#L429

Closes-Bug: bug/1400966

Note: Even this change could fully resolve the problem for Glance, but
we still need to fix this issue from glance_store perspective
separatelly due to other projects can use the lib directly.
