* Move ConnectionCache back to solana-client, and duplicate ThinClient, TpuClient there
* Dedupe thin_client modules
* Dedupe tpu_client modules
* Move TpuClient to TpuConnectionCache
* Move ThinClient to TpuConnectionCache
* Move TpuConnection and quic/udp trait implementations back to solana-client
* Remove enum_dispatch from solana-tpu-client
* Move udp-client to its own crate
* Move quic-client to its own crate
In the quic server handle_connection, when we timed out in receiving the chunks, we loop forever to wait for the chunk. If the client never provide another chunk, the server can hopelessly wait for that chunk and wasting server resources. Instead WAIT_FOR_CHUNK_TIMEOUT_MS is introduced to bound this to 10 seconds at maximum. The stream will be dropped if it times out.
* Time out async sends to avoid slackers stuck in the queue for too long
* Fixed a clippy error
* Added stats for timeout counts
* Link with stats correctly
* Add new empty crates and tpu_connection_cache module
* Add BaseTpuConnection trait and impl for udp and quic
* Add ConnectionPool trait and impl for udp and quic (quic-client doesn't build)
* Add a couple quic-specific apis to QuicConfig (from ConnectionCache)
* Re-export quic- and udp-client modules to prep for move
* Move ConnectionCacheStats to new module
* Move consts
* Duplicate ConnectionCache into tpu_connection_cache (doesn't build)
* Move methods to QuicConfig and remove unneeded methods (doesn't build)
* Genericize new ConnectionCache
* Rename new struct
* Copy unit tests (tests don't build)
* Fixup unit tests
* Move quic-specific test to quic-client crate
* DRY by using ConnectionPool method
* Prevent evicting pool about to be used
--tpu-enable-udp is introduced. And when this is on, the transaction receive and transaction forward is enabled using udp.
Except for a few tests which was hard-coded sending transactions using udp, most tests are being done with udp based tpu disabled.
