Code review comment for lp:~mpontillo/maas/allow-commissioning-non-lts

I forgot to add: the other reason you want to have this is for supportability. If suddenly the LTS no longer commissions but a non-LTS image is fine (or already has the fix, whatever the case may be), you want to have a way to allow users to use a non-LTS image in an emergency situation.

The other idea I had was, we could rename the option to "allow_commissioning_unsupported_releases", just to make it crystal clear that users who do this will get no support.
