Add ZeroMQ Support for output

[marshallmassengill]

Would love to see ZeroMQ supported as an output. It's a great way to manage messages and it is what we've been recommending to teams recently. Not perfect but it works well for a lot of use cases. Let us know how we can help!

Would we need to provide message definitions to teams so they could generate messages? What format is the data sent?

[marshallmassengill]

You can send just about anything. We typically are sending values for coordinates. I think you would need to provide some kind of information about the definition or type.
