Description of the problem, including code/CLI snippet

grp = gl.groups.get('example-group')

notif = grp.notificationsettings.get(sudo=otheruser)
print("Old level:", notif.level)

notif.level = gitlab.const.NOTIFICATION_LEVEL_GLOBAL
notif.save()    # missing sudo=otheruser

notif = grp.notificationsettings.get(sudo=otheruser)
print("New level:", notif.level)

Expected Behavior

I would expect this to change the notification level for the sudo'd user.

Actual Behavior

When I call notif.save(), it has seemingly no effect, because I am missing sudo.

Instead, the changes were applied to my admin account!

Changing the code to notif.save(sudo=otheruser) works as expected.

Specifications

• python-gitlab version: 1.4.0
• API version you are using (v3/v4): v4
• Gitlab server version (or gitlab.com): 10.6.4

Proposal

If an object is acquired using sudo=user, perhaps the library can attach that sudo user to the SaveMixin object, and automatically apply it when .save() is called without arguments.

I consider this a bug, and I can't imagine that anyone is actually relying on the current behavior.
