* Add new win_domain_group_membership module.
* Add support for diff mode.
* Do not assign variable which is never used.
* Add documentation for the `domain_*` options.
* Let ansible handle the exceptions.
The test if the group exists is useless as the first action on the
groups fails with the same error message if it does not exist.
* Add comments why we need the try/catch
* Rework diff handling.
Just return before/after state and let ansible do the working out of the
diff.
* Minor cleanups according to PR
* Switch from Get-AdUser/Group to Get-AdObject
so we can add/remove service accounts, or computers too.
* Cleanup PowerShell code
