Vote contract (#1552) 

* Add Vote Contract

* Move ownership of LeaderScheduler from Fullnode to the bank

* Modified ReplicateStage to consume leader information from bank

* Restart RPC Services in Leader To Validator Transition

* Make VoteContract Context Free

* Remove voting from ClusterInfo and Tpu

* Remove dependency on ActiveValidators in LeaderScheduler

* Switch VoteContract to have two steps 1) Register 2) Vote. Change thin client to create + register a voting account on fullnode startup

* Remove check in leader_to_validator transition for unique references to bank, b/c jsonrpc service and rpcpubsub hold references through jsonhttpserver
