* Keypair: implement clone()
This was not implemented upstream in ed25519-dalek to force everyone to
think twice before creating another copy of a potentially sensitive
private key in memory.
See https://github.com/dalek-cryptography/ed25519-dalek/issues/76
However, there are now 9 instances of
Keypair::from_bytes(&keypair.to_bytes())
in the solana codebase and it would be preferable to have a function.
In particular since this also comes up when writing programs and can
cause users to either start messing with lifetimes or discover the
from_bytes() workaround themselves.
This patch opts to not implement the Clone trait. This avoids automatic
use in order to preserve some of the original "let developers think
twice about this" intention.
* Use Keypair::clone
* 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
* Make sure to root local slots even with hard fork
* Address review comments
* Cleanup a bit
* Further clean up
* Further clean up a bit
* Add comment
* Tweak hard fork reconciliation code placement
* 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 in some CPU utilization metrics such as: number of vCPUs, clock frequency, average load across different time intervals, and number of total threads
Refactor the thin_client::create_client to take addresses separately instead of as a tuple

This PR renames BlockstoreAdvancedOptions to LedgerColumnOptions, as we will
pass-down this struct to LedgerColumn to allow it to perform metric reporting.
#### Summary of Changes
This PR further enables group by operation on storage type in blockstore_rocksdb_cfs metrics.
Such group-by allows us to further compare the performance metrics between rocks-level and
rocks-fifo.
To make things extensible, this PR introduces BlockstoreAdvancedOptions and move shred_storage_type.
All fields in BlockstoreAdvancedOptions will support group-by operation in blockstore_rocksdb_cfs.
Dependency: #23580
* Add quic-client module to send transactions via quic, abstracted behind the TpuConnection trait (along with a legacy UDP implementation of TpuConnection) and change thin-client to use TpuConnection
#### Summary of Changes
This PR adds two hidden arguments to the validator that allow users to use RocksDB's FIFO compaction for storing shreds.
--shred-storage <SHRED_STORAGE>
EXPERIMENTAL: Controls how RocksDB compacts shreds. *WARNING*: You will lose your ledger data
when you switch between options. Possible values are: 'level': stores shreds using RocksDB's default (level)
compaction. 'fifo': stores shreds under RocksDB's FIFO compaction. This option is more efficient on
disk-write-bytes of the ledger store. [default: level] [possible values: level, fifo]
--shred-storage-size <SHRED_STORAGE_SIZE_BYTES>
The shred storage size in bytes. The suggested value is 50% of your ledger storage size in bytes. [default:
268435456000]
Support using connection pooling and use multiple threads to do Postgres db operations. The performance is improved from 1500 RPS to 40,000 RPS measured during validator start.
Support multiple plugins at the same time.
