Issue MESOS-5954: Docker executor does not use HealthChecker library.
https://github.com/apache/mesos/commit/1556d9a3a02de4e8a90b5b64d268754f95b12d77 refactored health checks into a library. Command executor uses the library instead of the "mesos-health-check" binary, docker executor should do the same for consistency.
