Make composd API more async
Allow for notification on success/failure and for early cancellation.
Remove the old fully synchronous API.
Migrate the test to use the API (via modifying the composd_cmd tool).
Bug: 204044765
Test: atest ComposTestCase
Test: manual - make timeout very short, observe cancellation
