Add the builtin org.mobyproject.jobs.v0 extension, serving the Jobs API
on the daemon socket.
It is experimental and disabled by default; enable it with
extensions.enable (--extension-enable).
Run containers are driven through an Engine API client from the daemon
API point, and their exits observed through the container state point,
so restart-policy attempts do not count as exits.
Jobs persist through the storage point, and unnamed jobs are named
through the name-generator point.
Removing a run container also removes its anonymous volumes.
The extension host initializes before the daemon serves its API, so
activation reconciles runs and starts the scheduler in the background,
and the Jobs API answers Unavailable until then.
Shutdown releases blocked calls such as Wait, and waits for activation
and in-flight calls only until its deadline.
Authorization plugins are not supported yet, as the README states.
Integration tests cover a manual run, reconciliation after a killed
daemon, and the disabled extension.
A README next to the contract describes how to use it.
