minor tweaks
jetpants_collins: In Shard#sync_configuration, if shard is still in :initializing state, update its pool configuration asset as normal but do NOT update any fields on its DB nodes. This way, they will not get a secondary_role prematurely, which is helpful for monitoring setups that key on that field. Also means that other concurrent jetpants runs will ignore the child shards due to having no masters, which is good, since the masters arent set up yet at this point.
