Reduce pool size for ConnectionCache used by send-transaction-service to 2 from 4. No significant slow down of performance from bench-tps testing using rpc-client which is used by send-transaction-service. This will reduce active connections maintained both on the server and client. This will enable us to cache connections for more nodes.

Dynamic dispatch forces heap allocation and adds extra overhead.
Dynamic casting as in the ones below, lacks compile-time type safety:
https://github.com/solana-labs/solana/blob/eeb622c4e/quic-client/src/lib.rs#L172-L175https://github.com/solana-labs/solana/blob/eeb622c4e/udp-client/src/lib.rs#L52-L55
The commit removes all instances of Any, Box<dyn ...>, and Arc<dyn ...>,
and instead uses generic and associated types.
There are only two protocols QUIC and UDP; and the code which has to
work with both protocols can use a trivial thin enum wrapper.
With respect to connection-cache specifically:
* connection-cache/ConnectionCache is a single protocol cache which
allows to use either QUIC or UDP without any build dependency on the
other protocol.
* client/ConnectionCache is an enum wrapper around both protocols and
can be used in the code which has to work with both QUIC and UDP.

tpu-client/tpu_connection_cache is refactored out the module and moved to connection-cache/connection_cache and the logic in client/connection_cache is consolidated to connection-cache/connection_cache as well. client/connection_cache only has a thin wrapper which forward calls to connection-cache/connection_cache and deal with constructions of quic/udp connection cache for clients using them both.2.
The TpuConnection is refactored to ClientConnection to make it generic and functions renamed to be proper for other workflows. eg. tpu_addr -> server_addr, send_transaction --> send_data and etc...
The enum dispatch is removed so that we can make the bulk of code of quic and udp agnostic of each other. The client is possible to load quic or udp only into its runtime.
The generic type parameter in the tpu-client/tpu_connection_cache is removed in order to create both quic and udp connection cache and use the object to send transactions with multiple branching when sending data. The generic type parameters and associated types are dropped in other types in order to make the trait "object safe" for this purpose.
I have annotated the code explaining the reasoning and the refactoring source -> destination.
There is no functional changes
bench-tps has been performed for rpc-client, thin-client and tpu-client. And it is found the performance number largely match the ones before the refactoring.
