Original issue's description:
> Add src-side launcher for telemetry_unittests
>
> This will need a recipe-side change to pass the paths known to recipe
> (from the path recipe module) and properties (from the properties
> recipe module).
>
> Each of these key-value pairs is passed as two command line arguments,
> so that parsing them is easy and rock solid (avoids escaping issues),
> and is also easy to convert to dict python-side.
