Update interchaintest to support latest Hermes config

[rootulp]

Context

I'm trying to use interchaintest with Hermes relayer because the default ibc-go relayer is hitting #1055 and I don't know how to override the --gas flag for the command that is creating clients. I'm setting up the Hermes relayer like so:

	relayer := interchaintest.NewBuiltinRelayerFactory(
		ibc.Hermes,
		zaptest.NewLogger(t),
		relayer.CustomDockerImage("informalsystems/hermes", "v1.8.2", "1000:1000"),
	).Build(t, client, network)

Problem

It looks like the Hermes config in this repo doesn't match the latest Hermes config options.
