Subject: [PATCH] new: changes to enable daily-dangerous image builds

daily-dangerous image builds are standard desktop images for the devel
series, except all of the snaps are set to their respective edge
channels, and the dangerous model is used, hence its inclusion in this
commit.

Goes hand in hand with this MP:
