[SPARK-6050] [yarn] Add config option to do lax resource matching.
Some YARN configurations return a resource structure for allocated
containers that does not match the requested resource. That means
Spark would always ignore those containers. So add an option to relax
the matching of resources, so that users can still run Spark apps in
those situations.
