Autoconnect request confined-shell:hardware-observe

The confined-shell snap explores what is possible for a fully confined graphical shell.

Last year it was granted autoconnect for login-session-control and desktop-launch:

We’ve recently added indicators for battery & wifi. For these to work requires hardware-observe

@reviewers ping! Anyone?

Apologies @alan_g, this one slipped our radar as it was in the store category - not store-requests. I have now amended this.

+1 from me for auto-connect of hardware-observe for confined-shell as this is required for a standard use-case.

+1 from me to use hardware-observe for confined-shell snap.

Oops! Sorry, I don’t know how that happened (I do know better)

+2 for, 0 against. Granting the use of hardware-observe plug to this snap.

This is now live.
