Description

From a comment in MESOS-3771:

Master should not be storing the data fields from ExecutorInfo. We currently store the entire object, which means master would be at high risk of OOM-ing if a bunch of executors were started with big data blobs.

• Master should scrub out unneeded bloat from ExecutorInfo before storing it.
• We can use an alternate internal object, like we do for TaskInfo vs Task; see this.
