Hyperledger Fabric Orderer (Stateless - no local config)

Current orderer implementation is

1. Tightly coupled with reading config from local files
2. Using cryptogen before setting up orderer is unnecessary, however current impl forces one to do that
3. Not well documented
4. Tied to docker-compose
5. Bootstrapping orderer is complicated and requires co-ordinating files

This implementation reuses most parts of the existing orderer, but

1. cleans up the design
2. is loosely coupled and modular
3. is not tied to docker-compose
4. meant to run on Kubernetes
5. meant to aid dynamic addition of new orgs (orderers, peers, msps)

and Docs! expect a lot of Docs!
