Get a specific GPG key for a given user

Merged Michelle Gill requested to merge mgill-user-gpg into master

What does this MR do?

While removing authentication from the /user/:user_id/gpg_keys endpoint, I noticed that the documentation says we have an endpoint for /user/:user_id/gpg_keys/:key_id as well, which we do not. This MR provides support for showing a specific users individual GPG Key, which was not possible before even though it was documented.
