Support the IBC-go team with integrating Hermes into ibctest framework

[adizere]

Problem statement

The IBC-go team kindly asked us if we would be able to dedicate some time in assisting them to integrate Hermes into ibctest framework. I think we should help them.

The scope of the work for our team includes as follows:

• followup on PRs that IBC-go team opens in ibctest, I think @chatton will shoulder most of the work
• provide synchronous assistance in case Hermes CLIs are unclear
• provide PR review, suggestions, testing support
• optional: update Hermes documentation (maybe the features page?) to mention integration in ibctest

This issue is purely for tracking purposes. Likely we won't need to open a PR on the Hermes repo. All work will go in the ibctest repo.

Tasks

The docker images should be able to be built using a workflow similar to this one

We already have Docker images on Docker Hub at https://hub.docker.com/r/informalsystems/hermes/tags :)

Thank you @romac , it looks like these are already built and pushed on tags, this is all we needed!
