Description

We need an ability to insert events in a response stream. Currently, there is no way to spoof events on a response stream in the HTTP API for testing. Let's take an example:

A framework registers with the master and the master opens a persistent stream for sending events to the framework. It is presently impossible to insert events on this stream e.g., spoof a Event::ERROR from the master .

Previously, for old driver based frameworks using libprocess message passing we were able to invoke process::send to send such messages. This is also needed for spoofing events from agent->executor. In the future the internal master<->agent communication might also need this when we move it to the HTTP API.
