Create a Docker images and docker-compose for mining with Zebra on Testnet

[arya2]

Motivation

We could make it easier for people to try mining with Zebra on Testnet by publishing a Docker image.

This would also make it easier to add a manually dispatched workflow to our CI for testing mining pool support.

Design

Collect all of the steps for starting s-nomp and nheqminer zebra-instructions into Dockerfile(s).

Add a docker-compose file for starting zebra-mining-rpcs-testnet, redis, s-nomp, and nheqminer. (Exclude zebra-mining-rpcs-testnet from docker-compose so the rest of the instances can be spun up after the testnet sync?)

Timing

We're going to limit this ticket to 2 days of work, because it won't be usable in production. (We had to disable parts of s-nomp because it doesn't support NU5.)

This might have a lot of overlap with ticket #6025, can you update its ticket description to mention this ticket?

Is this a low priority or optional ticket?

If we do a "How to mine using s-nomp and Zebra on testnet" blogpost we would ideally provide the docker image already so I feel like this is potentially a blocker for finishing off #6028. However, we may decide that the instructions on there are good enough.

I think it's a should-have and medium priority so it can be included in the Zebra book.

Hey team! Please add your planning poker estimate with Zenhub @arya2 @conradoplg @dconnolly @oxarbitrage @teor2345 @upbqdn

This has a lot of overlap with #6200, we might want to make that Docker image first. I'll try to do that today.

@arya2 @mpguerra do we need to implement this ticket? Have any users asked for it?

s-nomp doesn't support generating its own NU5 coinbase transactions, so I'm not sure if we would want to create a Docker image that uses s-nomp. And I'm not sure if testnet images are useful to our users.

I don't think it's worthwhile anymore.
