Logging second order reasons for process starts
Currently the reason is described as the hosting type and name
of the lifecycle component that is being started. Adding a field to
describe the trigger that led to the component being invoked.
Starting with logging when an alarm caused a broadcast to start in the
app. Other examples of triggers that can be added are jobs for services,
push-messages for broadcasts, etc.
Test: make statsd_testdrive
