* Move finality computation into a service run from the banking stage, ComputeLeaderFinalityService
* Change last ids nth to tick height, remove separate tick height from bank
* 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
Deserialize operations are faster when done serially with the
MT banking stage and helps with performance improvement with
reduced thread context switches.
* Added tests to thin client to test VoteContract calls, fix VoteContract sizing errors
* Calculate upper bound on VoteProgram size at runtime, add test for serializing/deserializing a max sized VoteProgram state
* 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
Addresses the following problem
- Validators are not able to keep up with the leader
- The future blobs (outside of window) get dropped
- The validators won't process repair requests for these future blobs
