Remove ION dependency

[mfarina1]

Take ION out of the containers. The dependency is on the Manager, but we hypothesized that we can take out the elements of the Manager into the RefDM, which would not rely on ION at all, and the RefDM could live inside our container(s).

Only technical difficulty is that Docker and Podman don't want connections going from inside the container to the host, and we have to figure out how to allow that to happen. Do we have a supported way of addressing the host as a host?

This work will likely entail creating a new protocol.
