Allow read / write tokens to be added to all repos by default



currently if i want to have circle do automerging of branches i need to first add my user token to the repo. we have a lot of repos and this quickly becomes tedious. would love if there were an option to have the deploy token default to being read write or somehow auth all repos with the same github user token. (in general having some basic cross repo config would be a HUGE time saver. especially sharing things like aws creds, npm tokens, etc)
