I have two questions.
First, does this change include the executor library? We currently use
environment variables to propagate various config values from an agent to
executors. If it does, what is the alternative?
Second, what will be the preferred way to pass config values to executors?
It would be great to be able to do it uniformly for non-HTTP and HTTP
executors. I can think of several possibilities: cmd flags, adding or
overriding protobufs, extending Executor interface.
