Upgrade puppet for module command.
Upgrade puppet for module command.

unattended upgrades is not upgrading puppet on the slaves
in our cron jobs because we've changed puppet.conf. This brings up a
question. But, if we don't have the puppet module command, things
go poorly here - so check to see if we have it, and if not,
do an install forcing old conf values.
