Motivation

In order to test against mainnet entirely locally, outside of dev-mode this PR does the following:

  1. changes some assumptions for peers with loopback addresses to allow a peer bound on 127.0.0.1 to connect to a peer bound on 127.0.0.2 without sharing loopback address peers with non-local peers
  2. allows for specifying bootstrap peers with the BOOTSTRAP_PEERS=127.0.0.2,127.0.0.3 environment
  3. allows for specifying custom generated genesis blocks via snarkos start --genesis ./path/to/block.genesis

This collection of features also empowers end users to create more dynamic isonets for their own internal testing of snarkOS.

To use these changes, simply specify BOOTSTRAP_PEERS=127.0.1.2 before your start command, and specify the loopback address in --node 127.0.1.2:3030 or --bft 127.0.1.2:5000.

Here is a genesis block generated by the aot command from the snarkops project that can be used for a simple 4 validator mainnet
(--network 0) along with the committee's keys and some generated keys for running client nodes.

My topology is as follows (ports omitted in the table)

BOOTSTRAP_PEERS=127.0.2.1:4130,127.0.2.2:4130,127.0.2.3:4130,127.0.2.4:4130

Validators are peered with bootstrap peers, fringe clients rely on bootstrap peers for peering.
