Bug Description
[Impact]
When a user is logged in to the Ubuntu desktop, a power button event will cause the user to be prompted to choose if they'd like to proceed with a shutdown. However, if the system is sitting at a greeter screen, a power button event will instead attempt a suspend w/o prompting. This is due to a different set of defaults for the greeter and the user.
This is a fix for this, aligning all power actions between the greeter behaviour and the user session one on the user session.
[Test Plan]
1. Install new package and reboot
2. On the greeter screen (gdm), press the physical power button of your machine.
3. You should be now prompted about what to do, like shutdown. You can dismiss it.
4. Clicking on the physical suspend button should suspend the machine immediatly.
[Where problems could occur]
We change the scope of when we applied those settings: we were only applying them to the GNOME session ran by the user, and it will now be applied as default to the GNOME session ran by gdm.
Impacts is thus limited to the greeter screen.

Original report content:
For a logged-in desktop user, they
see:
$ gsettings get org.gnome.
power-button-action 'interactive'
But the gdm user sees:
$ sudo machinectl shell gdm@ /bin/bash
Connected to the local host. Press ^] three times within 1s to exit session.
gdm:~$ gsettings get org.gnome.
'suspend'
Changing the gdm user's setting to "interactive" using gsettings causes the greeter to begin prompting, consistent with the logged in user experience.

Issue here I think is that we use per-session overrides for the majority of our Ubuntu customisations, and these don't apply to greeter sessions.
