testing: Add kurtosis eth harness.

[JoeGruffins]

This should let us hook up base for simnet. I think it's a good alternative to using --dev anyway as it is closer to eth mainnet.

How will you hook up base on top of this?

Base needs access to the consensus node and execution node to run. I'm not sure yet if it will run without problems but it does run on top of this. However it requires ignoring some starting validation, so we will need to fork https://github.com/ethereum-optimism/optimism and comment out a couple lines. Then just point it at the endpoints.

With the --dev flag we are not getting the consensus node currently you know.

OK that makes sense, I think this is good.

I'm getting this error when running the harness:

Is this not happening for you? I think you need to install these packages within the docker containers.

[JoeGruffins]

@martonp did you run npm install in the harness dir first?

[JoeGruffins]

Actually maybe I have that installed globally? I think I need to add it to the package.json, doing that

[JoeGruffins]

Sorry, can you run npm install again and try again https://github.com/decred/dcrdex/compare/ab1a8e6692a7b03d9f03c0ec643a552f42279ebb..0cc4f775e464b475c2240aaf9ecbeb4427d423ef

[JoeGruffins]

Actually adding base on top of this may be more complicated than I thought.
