This only has the one service, why specify android::process? Or does it run
separately from the Driver. If so, is that really desirable? I worry that the
ReportingService will get killed for some reason and we fail to collect results.

I imagine another way this could be done is with BroadcastReceivers. You could
have one here in the driver which would just listen to broadcasts of events
which the broker would supply. If you're concerned about potential crosstalk
between apps, you could have an identifier for each run that's included with the
test result. I'm not sure that it's strictly better, but does simplify the
service connection part and removes a process. wdyt?

Switched from service to dynamically registered BroadcastReceiver. This dropped
~200 lines from this CL and is much simpler.
