* 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.
* Add PoH height to process_ledger()
* Moved broadcast_stage Leader Scheduling logic to use Poh height instead of entry_height
* Moved LeaderScheduler logic to PoH in ReplicateStage
* Fix Leader scheduling tests to use PoH instead of entry height
* Change is_leader detection in repair() to use PoH instead of entry height
* Add tests to LeaderScheduler for new functionality
* fix Entry::new and genesis block PoH counts
* Moved LeaderScheduler to PoH ticks
* Cleanup to resolve PR comments
Generate tick entry ids and only register ticks as the last_id expected by the bank. Since the bank is MT, the in-flight pipeline of transactions cannot be close to the end of the queue or there is a high possibility that a starved thread will encode an expired last_id into the ledger. The banking_stage therefore uses a shorter age limit for encoded last_ids then the validators.
Bench client doesn't send transactions that are older then 30 seconds.
* Added LeaderScheduler module and tests
* plumbing for LeaderScheduler in Fullnode + tests. Add vote processing for active set to ReplicateStage and WriteStage
* Add LeaderScheduler plumbing for Tvu, window, and tests
* Fix bank and switch tests to use new LeaderScheduler
* move leader rotation check from window service to replicate stage
* Add replicate_stage leader rotation exit test
* removed leader scheduler from the window service and associated modules/tests
* Corrected is_leader calculation in repair() function in window.rs
* Integrate LeaderScheduler with write_stage for leader to validator transitions
* Integrated LeaderScheduler with BroadcastStage
* Removed gossip leader rotation from crdt
* Add multi validator, leader test
* Comments and cleanup
* Remove unneeded checks from broadcast stage
* Fix case where a validator/leader need to immediately transition on startup after reading ledger and seeing they are not in the correct role
* Set new leader in validator -> validator transitions
* Clean up for PR comments, refactor LeaderScheduler from process_entry/process_ledger_tail
* Cleaned out LeaderScheduler options, implemented LeaderScheduler strategy that only picks the bootstrap leader to support existing tests, drone/airdrops
* Ignore test_full_leader_validator_network test due to bug where the next leader in line fails to get the last entry before rotation (b/c it hasn't started up yet). Added a test test_dropped_handoff_recovery go track this bug
