What does this PR do?
contribroutines, which contains astopchannel and an API for getting the channel and closing the channel. The contribs should get the channel to use as a stop condition for any goroutines they launch, and the tracer should be the only one to stop the channel.Motivation
We needed a way for the tracer to stop any goroutines that it does not directly manage on tracer.Stop(); without such a mechanism, we were dealing with runaway goroutines.
