WIP: Json rpc federation, search/getclaimbyid, and shutdown (#76)

Browse source 
* Cleanup shutdown and peers subscribe

this has errors currently, need to figure out data race

* fixed data race finally....

* getclaimbyid and search

* hook jsonrpc peers subcribe into current federation

* cleanup some peers stuff

* remove commented code

* tie into session manager in jsonrpc peers subscribe

* use int for port args

* cleanup and fix a bunch of compiler warnings

* use logrus everywhere

* cleanup test
