mir-kiosk snap: https://dashboard.snapcraft.io/dev/snaps/6225/
We want to deprecate the use of mir-libs content snap as the provider of mir-libs content and consolidate it instead with mir-kiosk snap itself. This will be bit less confusing to users of mir-kiosk.
mir-libs content snap currently has Auto-connection enabled for its mir-libs slot. We would like mir-kiosk:mir-libs to have Auto-Connection enabled as mir-libs content snap has.
