Update grenade setting on current master

grenade is branched for stable/2023.1, so updating
the current master default setting for:
- Update grenade testing from stable/2023.1 to master.
- Update grenade-skip-level job not to run for current non SLURP master
release

octavia-grenade job is broken due to diskimage-builder so to unblock
grenade gate, stop running it and we can run it once DIB fix is merged
and released
