mod_adhoc_oauth2_client: Fix including final client_id in result form The client_id is composed of the details needed for retrieving the data, making it redundant to include in the data, albeit somewhat convenient sometimes. Decided to remove it anyways, but forgot to change the result.

mod_adhoc_oauth2_client: Add stub README

mod_http_oauth2: Improve storage of client secret Note well: This is still a thing for developers, do not panic!

mod_adhoc_oauth2_client: Note TODO

mod_adhoc_oauth2_client: Allow creating OAuth2 clients via ad-hoc To go with mod_http_oauth2

mod_http_oauth2: Rescope oauth client config into users' storage This produces client_id of the form owner@host/random and prevents clients from being deleted by registering an account with the same name and then deleting the account, as well as having the client automatically be deleted when the owner account is removed. On one hand, this leaks the bare JID of the creator to users. On the other hand, it makes it obvious who made the oauth application. This module is experimental and only for developers, so this can be changed if a better method comes up.
