* update banking-bench to simulate mint event by specifying certain percentage of conflicting transactions with higher priority fee
* set proper compute-unit for transfer transactions
- Forward packets by prioritization in desc order
- Add support of cost-tracking by transaction requested compute units
- Hook up account buckets to forwarder
- Add metrics for forwardable batches count
- Remove redundant invalid packets filtering at end of slot since forwarder will do the same when batch forwardable packets
- Add bench test for forwarding
* Remove UseQuic type
Move to storing the UdpSocket on ConnectionCache and accepting a bool
* Remove use_quic from ConnectionCache constructor
Replace with separate with_udp constructor to force callers to choose
* Define shuffle to prep using same shuffle for multiple slices
* Determine transaction indexes and plumb to execute_batch
* Pair transaction_index with transaction in TransactionStatusService
* Add new ReplicaTransactionInfoVersion
* Plumb transaction_indexes through BankingStage
* Prepare BankingStage to receive transaction indexes from PohRecorder
* Determine transaction indexes in PohRecorder; add field to WorkingBank
* Add PohRecorder::record unit test
* Only pass starting_transaction_index around PohRecorder
* Add helper structs to simplify test DashMap
* Pass entry and starting-index into process_entries_with_callback together
* Add tx-index checks to test_rebatch_transactions
* Revert shuffle definition and use zip/unzip
* Only zip/unzip if randomize
* Add confirm_slot_entries test
* Review nits
* Add type alias to make sender docs more clear
* Connection pool in connection cache and handle connection errors
1. The connection not has a pool of connections per address, configurable, default 4
2. The connections per address share a lazy initialized endpoint
3. Handle connection issues better, avoid race conditions
4. Various log improvement for help debug connection issues
* client: Remove static connection cache, plumb it instead
* Add TpuClient::new_with_connection_cache to not break downstream
* Refactor get_connection and RwLock into ConnectionCache
* Fix merge conflicts from new async TpuClient
* Remove `ConnectionCache::set_use_quic`
* Move DEFAULT_TPU_USE_QUIC to client, use ConnectionCache::default()
Upcoming changes to PacketBatch to support variable sized packets will
modify the internals of PacketBatch. So, this change removes usage of
the internal packet struct and instead uses accessors (which are
currently just wrappers of Vector functions but will change down the
road).
- Add write-lock-contention option, replacing same_payer
- write-lock-contention also has a same-batch-only value, where
contention happens only inside batches, not between them
- Rename num-threads to batches-per-iteration, which is closer to what
it is actually doing.
- Add num-banking-threads as a new option
- Rename packets-per-chunk to packets-per-batch, because this is closer
to what's happening; and it was previously confusing that num-chunks
had little to do with packets-per-chunk.

- decouple cost_model from cost_tracker; allowing one cost_model
instance being shared within a validator;
- update cost_model api to calculate_cost(&self...)->transaction_cost
