Subject: [PATCH] [REF] resource: remove deprecated compatibility and rename
 methods

Old methods are still present since a long time and are deprecated since
saas-3. This compatibility layer adds unnecessary complexity to the module
API. Those methods should now be removed. Some renaming is also performed
to ease resource api understanding, notably to better differentiate
internal methods from other methods.

All addons are updated accordingly.
