Support dev mode for Fabric v3

- Dev mode in Fablo works for solo consensus and TLS disabled only
- Also Fablo supports RAFT consensus with TLS only
- Fabric v3 drops support for solo consensus, so we need to use RAFT

So the question is how to support dev mode for Fabric v3, and:
1. It seems we need to use RAFT
2. We don't know if we should use TLS, maybe it should be RAFT with no TLS
3. This might be useful sample for profile: https://github.com/hyperledger/fabric/blob/main/sampleconfig/configtx.yaml#L608
4. We should have bash test that verifies if dev mode works
