Review request for mesos, Jie Yu and Joseph Wu.
Bugs: MESOS-8183
https://issues.apache.org/jira/browse/MESOS-8183
Repository: mesos
Description
-------
The `ContanierDaemon` class is responsible to monitor if a long-running
service running in a standalone container is ready to serve, and restart
the service container if not. It takes the following 3 hook functions:
* `preStartHook`: called prior to container launch.
* `readinessHook`: called periodically to check if the service is ready.
If a duration is returned, it serves as a backoff period, meaning that
the next check will be scheduled after the duration. It can also be
used to set up futures to reflect the readiness of the status outside
the container daemon.
* `postStopHook`: called after the container is killed.
`ContainerDaemon` does not manage the lifecycle of the contanier it
monitors, so the container persists across `ContainerDaemon`s. However,
it provides a `terminate()` method to completely shutdown the monitoring
container.
