feat(p2p): request response skeleton

[Maddiaa0]

Overview

Part of #7964

This is a minimal implementation of the guts of a request and response protocol that dials the connected peers and asks for a given data.

The current design relies on the protocol mapping, which maps a protocol to a handler, the idea being that this service will be wrapped by the larger p2p client
which will have direct access to the relevant tx / attestation pools.

No metrics with a significant change found.

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.
