* Move more of the replicator logic into the replicator class
* Add support for the RPC interface to query the storage last_id value
that the replicator would sign and use to pick a block.
* Fix replicator connecting to gossip and change test to exercise that
scenario.
* Set drone address to always be the initial network entry point, so that even when leaders rotate the client can still find the drone
* Extract drone address as a separate argument to bench-tps
* Add drone port to client.sh instead of setting it in bench-tps
* Add drone entrypoint to scripts
* Fix build error
* Cluster Replicated Data Store
Separate the data storage and merge strategy from the network IO boundary.
Implement an eager push overlay for transporting recent messages.
Simulation shows fast convergence with 20k nodes.
That's supposed to be an ASCII format, but we're not making use
of it. We can switch back to that some day, but if we do, it shouldn't
be JSON-encoded.
* Add first leader to genesis entries, consume in genesis.sh
* Set bootstrap leader in the bank on startup, remove instantiation of bootstrap leader from bin/fullnode
* Remove need to initialize bootstrap leader in leader_scheduler, now can be read from genesis entries
* Add separate interface new_with_leader() in mint for creating genesis leader entries
* 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
* Use IV to make unique identies
* Use hex! macro for hex literal and not string converted to u8 slice
* fix sha sampling to control init/end of sha state
* Move ledger write to its own stage
- Also, rename write_stage to leader_vote_stage, as write functionality
is moved to a different stage
* Address review comments
* Fix leader rotation test failure
* address review comments
