SPARK-13688: Add spark.dynamicAllocation.overrideNumInstances.
When both the number of executor instances and dynamic allocation are
configured, dynamic allocation is ignored and the number of executors is
statically set. This introduces a configuration property to change this
behavior so that cluster administrators can make dynamic allocation the default
when users set `--num-executors` instead of
`spark.dynamicAllocation.minExecutors` and unintentionally disable dynamic
allocation for a job.
This includes unit tests for the new cases and updates to documentation.
