Currently, when we save a Rule, we get a popup that says something like "Rule saved successfully".

However, if there is either 0 Directives or 0 Groups selected, this Rule will not actually do anything. This can be very confusing to new users who didn't realize how this screen works.

This user story should add a small warning to the confirmation popup, so it reads somethings like this:

--------------8<----------------------
Rule saved successfully*
WARNING: This Rule is not applied to any Groups. No configuration policy will be deployed.**
--------------8<----------------------

• Don't change this text, leave it as is, I just don't remember it right now
  • If there are groups but not Directives, this should read "This Rule does not have any Directives to apply. No configuration policy will be deployed."
