[chatton]

This PR is not necessarily intended to be merged, it contains a bunch of bash scripts / docker compose to spin up an environment to be able to test the ibc transition.

Here are the steps I performed.

make up

Spins up 3 chains, the hermes relayer, and creates clients/connections/channels between chain-a -> chain-b and chain-a- > chain-c
