Handle device actions for metric collectors

This change introduces two ITestDevice api methods that will allow
metric collectors to register themselves to receive device events like
reboot. It also introduces an Interface declaring all the device events
that can be received.

This change includes implementation to report reboot start and end
events to all device event receivers. It also makes sure that these
event callbacks don't enter a dead loop.

This change also includes required changes to DeviceTraceCollector to
enable this feature.

Test: Presubmit, "run host --class com.android.tradefed.presubmit.DeviceStateTransitionFuncTests --auto-collect DEVICE_TRACE"

Trade Federation (TF / Tradefed)

TF is a test harness used to drive Android automated testing. It runs on test hosts and monitors the connected devices, handling test scheduling & execution and device management.

Other test harnesses like Compatibility Test Suite (CTS) and Vendor Test Suite (VTS) use TF as a basis and extend it for their particular needs.

Building TF:

  • source build/envsetup.sh
  • tapas tradefed-all
  • make -j8
