/**
* This module chooses the correct telemetry controller module to load
* based on the process:
*
* - TelemetryControllerParent is loaded only in the parent process, and
* contains code specific to the parent.
* - TelemetryControllerContent is loaded only in content processes, and
* contains code specific to them.
*
* Both the parent and the content modules load TelemetryControllerBase,
* which contains code which is common to all processes.
*
* This division is important for content process memory usage and
* startup time. The parent-specific code occupies tens of KB of memory
* which, multiplied by the number of content processes we have, adds up
* fast.
