This adds a setting to data frame analytics jobs called `max_number_threads`. The setting expects a positive integer. When used the user specifies the max number of threads that may be used by the analysis. Note that the actual number of threads used is limited by the number of processors on the node where the job is assigned. Also, the process may use a couple more threads for operational functionality that is not the analysis itself. This setting may also be updated for a stopped job. More threads may reduce the time it takes to complete the job at the cost of using more CPU.
