Remove puppetdb storeconfig setting

By default, puppetdb wants to manage and turn on storeconfigs in
puppet.conf. We have no use for this option, and it's turned off
in our puppet.conf - so the setting is fighting the file - causing
every single run of puppet to fight itself. Turn the setting off.
