Requirements:

• Backwards-compatible interface w/ current Bitswap impl, so that this can be integrated easily and provide feedback
• Wire into Kubo
• Add configuration so can function as as just a bitswap client or bitswap server
• Passes a basic test w/ a test harness
  • It's okay for edge cases to be missing, this task is about setting up the scaffolding and feedback loop needed to complete Separable client and server implementations #564
  • Two tests
    • Private network of nodes
      • This is so we have a place to test specific scenarios
    • Peer w/ ipfs.io gateways and handle Bitswap reqs from gateways
      • So that we can test against realistic production traffic

The intention was to deploy this to a cluster to get some perf feedback, but that is looking harder than anticipated, so we should just bite the bullet and setup a proper test harness as part of this.
