fix boot node instability issue, refactor p2p host configurations and add new features to p2p

Issue

After upgrading the boot nodes to the latest version of the main branch, which includes several changes compared to the previous boot node code, the boot node service process began restarting repeatedly. This was accompanied by numerous error messages related to the QUIC protocol, noise, sessions, muxers, and various other lower layer P2P issues.

This PR addresses these issues by making the following changes:

Removes QUIC, an unnecessary feature, and switches to TCP transport.
Makes TLS/Noise, relays, and NAT optional features that can be disabled via configuration.
Adds a dial timeout for the connection manager.
Allows the use of the MPlex muxer in addition to Yamux.

Additionally, this PR introduces several new configurations and flags, detailed below: NoTransportSecurity: to disable p2p security (tls and noise) NAT: enable p2p NAT. NAT Manager takes care of setting NAT port mappings, and discovering external addresses UserAgent: custom user agent; explicitly set the user-agent, so we can differentiate from other Go libp2p users DialTimeout: p2p dial timeout MuxerType: P2P multiplexer type (default:Mplex, 0:Mplex, 1:Yamux) NoRelay: No relay services, direct connections between peers only
