This is great - thank you! I just had a comment relative to naming and units.

I'd prefer we follow the naming (and units) convention that @esevan introduced in jupyter/nb2kg#29. Let's call the option ws_ping_interval (with the help string indicating seconds) and the env variable EG_WS_PING_INTERVAL_SECS (defaulting to 30), then expand to ms on usage.

I don't think we need to mention ZMQ since that corresponds more closely to the (multiple) ZMQ ports - we're really pinging the (single) WS port.
