Coinbase Rosetta Support

[faddat]

We should attempt to support the Coinbase Rosetta API standard.

The Dockerfile part, I've completed here:
https://gitlab.com/faddat/vsys-docker/-/blob/master/Dockerfile

I did that following this guidance:
https://www.rosetta-api.org/docs/node_deployment.html#good-example

Probably, to be compliant, it would be a good idea to fix #208 and merge #214

For the actual structuring of a rosetta API, there is an introduction here:

https://www.rosetta-api.org/docs/node_api_introduction.html

The Coinbase Rosetta spec is here:

The Coinbase Rosetta forums are here:
