* add subcommand to set randomized compute-unit-price to transactions.
* add compute-unit-limit to limit additional cost from prioritization.
* increase funding if use_randomized_compute_unit_price is enabled.
* 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()
* Add fallible send methods, and rpc_client helper
* Add helper to return RpcClient url
* Implement BenchTpsClient for TpuClient
* Add cli rpc and identity handling
* Handle different kinds of clients in main, use TpuClient
* Add tpu_client integration test
* Add BenchTpsClient
* Impl BenchTpsClient for used clients
* Use BenchTpsClient in do_bench
* Update integration test to use faucet via rpc
* Support keypairs from file that are not prefunded
* Remove old perf-utils
* SDK: Split new `FeeRateGovernor` out of `FeeCalculator`
Leaving `FeeCalculator` to *only* calculate transaction fees
* Replace `FeeCalculator` with `FeeRateGovernor` as appropriate
* Expose recent `FeeRateGovernor` to clients
* Move `burn()` back into `FeeCalculator`
Appease BPF tests
* Revert "Move `burn()` back into `FeeCalculator`"
This reverts commit f3035624307196722b62ff8b74c12cfcc13b1941.
* Adjust BPF `Fee` sysvar test to reflect removal of `burn()` from `FeeCalculator`
* Make `FeeRateGovernor`'s `lamports_per_signature` private
* rebase artifacts
* fmt
* Drop 'Recent'
* Drop _with_commitment variant
* Use a more portable integer for `target_signatures_per_slot`
* Add docs for `getReeRateCalculator` JSON RPC method
* Don't return `lamports_per_signature` in `getFeeRateGovernor` JSONRPC reply
* SDK: Refactor (read|write)_keypair
Split file opening and data writing operations
Drop filename == "-" stdio signal. It is an app-level feature
* keygen: Move all non-key printing to stderr
* keygen: Adapt to SDK refactor
* keygen: Factor keypair output out to a helper function
* implement per-thread, per-batch sleep in ms (throttling allows easier UI development)
* tidy up sleep() call with Duration::from_millis() instead of Duration::new()
* fixup indentation style
* removing multinode-demo/client-throttled.sh (same functionality available via arguments)
