We install microk8s via snap pulling information from snapcraft.io.
Unfortuantely, this service seems to be having issues serving data
resulting in errors like:
error: cannot install "microk8s":
Post "https://api.snapcraft.io/v2/snaps/refresh": context canceled
Manually browsing snapcraft.io also produces incomplete data and
unrendered pages. While this is happening make these jobs non voting so
that we can land other changes.
