Add cardano-tracer and tracer-sidecar images

[Anviking]

This PR adds a cardano-tracer image and container to the example stack, along with some documentation on how to use it. It does not (yet) leverage the existence of the tracer to write test templates and express properties.

fix #4

includes #11

I don’t think you should use a separate Docker image for building the tracer image. It takes more than an hour to build everything already and if we start to build every image with cardano-node (we may want relays, dbsync etc in the future) it will take for ever.

You need to add the image in the json to the anti build target for the tracer image to be used by antithesis.

Is this PR still problematic? (apart from the fact it conflicst with base branch)

As discussed, it should only need to be built once, and not need to be rebuilt even if we change the revision of the cardano-node image etc.

Done.

I don't think so — I ran example_10.2.1 with #11 included and it still works also.

Ok, actually not included in this PR atm 👀 now merged though

So I guess this is good to go?

Yes, it should be good to go, just waiting on approval (or at least absence of objections) from @karknu

[abailly]

It does not impact @karknu 's tests so I guess we can move on. merging.
