🎯 Problem to be solved

Verify the connectivity and health of peer-to-peer connections within the Charon cluster.

🛠️ Proposed solution

  • Start libp2p node, connect to relay and subsequently to other libp2p nodes
  • Implement a test to check if our node can ping all other nodes
  • Implement a test to measure packet loss between peers
  • Implement a test to measure round-trip time (RTT) between peers
  • Accumulate and evaluate the peer-to-peer connection test results, contributing to the overall cluster health assessment
  • Include the peer-to-peer connection test results in the report

cmd: alpha test peers tests (#3039)
21d34cc 
Continuation of the epic for `alpha test` command.

In this PR are included:
- Start of TCP libp2p node.
- Connection to other peer nodes (using hash of the ENRs as an ID for the relay).
- Launching 3 ping tests towards peers:
  - Ping - regular ping done only once. It blocks the rest of the peer tests. We assume that if we cannot successfully ping a peer, there is no reason to execute any other tests against that peer.
  - PingMeasure - regular ping done only once, measuring the RTT. RTT is considered either good, average or bad.
  - PingLoad - continuous pings, spawning each second a new go routine doing pings, measuring the RTT of each one of them. The RTT is considered either good, average or bad. Worst observed RTT is picked as a resulting value.
- Keeping the TCP node alive (configurable by a flag), in order other peers to be able to conduct tests on their end.

N.B.: There are some hardcoded values that are subject to change:
- Threshold for good/average/bad for PingMeasure test (currently set to 200/500ms);
- Threshold for good/average/bad for PingLoad test (currently set to 200/500ms);
- Await time between ping attempts in Ping test, when peer is not reachable (currently set to 3s);
- Await time between pings in PingLoad test per go routine (currently set to random value between 0 and 100ms);

Not in scope of this PR:
- Tests against self
- More elaborate tests towards peers - direct/indirect connections, packet loss, etc.
