* 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
Budget now assumes the source account holds all tokens the program
should spend.
Note: the static guarantees implied by verify_plan() are meaningless
under the new contract engine. The bank no longer calls it. This
serves as a nice example of where comparing code coverage between
integration tests and unit tests would have shown us where a
change rendered unit tests meaningless.
Debits no longer need to be applied before credits. Instead, we
lock any accounts we'd debit and so error out on the second attempt
to lock the same account.
In the old bank (before the contract engine), Contract wasn't specific
to Budget. It provided the same service as what is now called
SystemProgram::Move, but without requiring a separate account.
