Integrate Hermes into our E2E tests

[chatton]

Summary

hermes support has been added to interchain test so we can now wire up hermes as an option in our tests.

In order to do this, we need to

1. Create the relayer implementation here
2. Choose a default version to be set here
3. Add hermes as a relayer type in our compatibility tests
4. Decide if we want to use hermes as default, or both hermes and rly. To specify a default, we can add a field to the workflow.

This work can be done after #3314
