[SPARK-21563][CORE] Fix race condition when serializing TaskDescriptions
and adding jars
## What changes were proposed in this pull request?
Fix the race condition when serializing TaskDescriptions and adding jars by
keeping the set of jars and files for a TaskSet constant across the lifetime of
the TaskSet. Otherwise TaskDescription serialization can produce an invalid
serialization when new file/jars are added concurrently as the TaskDescription
is serialized.
## How was this patch tested?
Additional unit test ensures jars/files contained in the TaskDescription
remain constant throughout the lifetime of the TaskSet.
