Even if there are many connections with stake less than the
threshold_stake, prune_random might still reject if both randomly
sampled connections have stake bigger than the threshold. A bigger
sample-size will make this less likely (at the cost of more
computations):
https://github.com/solana-labs/solana/blob/2cbd5d6c9/streamer/src/nonblocking/quic.rs#L958-L985
In order to benchmark for an optimal sample-size, the commit generalizes
the sample-size and makes it configurable.

Allow longer chunk receive timeout without impacting testing the stream exit condition for unit tests. The exit is periodically checked, we will break only when the total allowed chunk receive timed out. The start time is reset when a new chunk is received.
* Support bi-directional quic communication, use the same endpoint for the quic server and client
This is needed for supporting using quic for repair
* Added comments on the bi-directional communication tests
* Removed some debug logs
* clippy issue
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.
Tenets:
1. Limit thread names to 15 characters
2. Prefix all Solana-controlled threads with "sol"
3. Use Camel case. It's more character dense than Snake or Kebab case
This change sets the receive_window for non-staked node to 1 * PACKET_DATA_SIZE, and maps the staked nodes's connection's receive_window between 1.2 * PACKET_DATA_SIZE to 10 * PACKET_DATA_SIZE based on the stakes.
The changes is based on Quinn library change to support per connection receive_window tweak at the server side. quinn-rs/quinn#1393
