Move `groups` package under `resources` package

With user groups being resources that users can act on (with the
recent changes), this commit moves the `groups` module to under the
`resources` module.

It also renames the `*_resources.py` modules by dropping the
`_resources` part since the code is under the `resources` module
anyway.
