Cannot start agent and collector on the same machine (OpenTelemetry distribution)

[jpkrohling]

When trying to start both the collector and the agent on the same machine, the second component to start hangs without failing:

$ SPAN_STORAGE_TYPE=memory go run ./cmd/collector 

In another terminal:

$ go run ./cmd/agent --reporter.grpc.host-port=localhost:14250

^Csignal: interrupt

Once #2563 is addressed, this won't be such a big problem, as the port can then be overridden.

the second component to start hangs without failing

odd, since when port is in use you normally get an error and the binary should exit with it

[jpkrohling]

That'd be my expectation too.
