* 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
This reduces how much memory is written to last_id_sigs table on very TX, and has a 40% impact on
`cargo +nightly watch -x 'bench bench_banking_stage'`
See #1157 for details. The `from` account should be cloned
before execute_transaction(), and that's the only one that should
be stored if there's an error executing the program.
lastidnotfound step 2:
* move "record stage", aka poh_service into banking stage
* remove Entry.has_more, is incompatible with leader rotation
* rewrite entry_next_hash in terms of Poh
* simplify and unify transaction hashing (no embedded nulls)
* register_last_entry from banking stage, fixes#1171 (w00t!)
* new PoH doesn't generate empty ledger entries, so some fixes necessary in
multinode tests that rely on that (e.g. giving validators airdrops)
* make window repair less patient, if we've been waiting for an answer,
don't be shy about most recent blobs
* delete recorder and record stage
* make more verbost thin_client error reporting
* more tracing in window (sigh)
* Add hooks for executing the storage contract
* Add store_ledger stage
Similar to replicate_stage but no voting/banking stuff, just convert
blobs to entries and write the ledger out
* Add storage_addr to tests and add new NodeInfo constructor
to reduce duplication...
