 * @brief The number of recyclable jobs for the task pool to cache.
 *
 * Caching dynamically allocated jobs (recyclable jobs) helps the application
 * to limit the number of allocations at runtime. Caching recyclable jobs may
 * help making the application more responsive and predictable, by removing a
 * potential for memory allocation failures, but it may also have negative
 * repercussions on the amount of memory available at any given time. It is up
 * to the application developer to strike the correct balance among these
 * competing needs. The task pool will cache a job when the application calls
 * IotTaskPool_RecycleJob on a job which was created using
 * IotTaskPool_CreateRecyclableJob API. Any recycled jobs in excess of
 * IOT_TASKPOOL_JOBS_RECYCLE_LIMIT will be destroyed and its memory will be
 * released.

 * Default value (if undefined): 8

 * task pool, each of which uses statically allocated memory to ensure creation
