Description

We should build a TCP server sink that clients can connect to and receive events in a streaming fashion. It should probably have a throttler built in (see #258) and potentially a way to dynamically request other sampling options.

The initial implementation can be mostly a dumb pipe, but we should plan to enhance this to support structured data and build a client that knows how to pretty print it. Further down the line, we'll want it to support tailing metrics rollups as well (think dstat).

Research direction

No files, tests, or entry points are named. Start by locating the existing sink implementations and the pipeline's event-streaming interfaces; done would mean a TCP server sink that lets clients receive events as a basic stream, while throttling, structured data, clients, and metrics rollups remain future work.
