ThreadPoolOptionProtoOrBuilder

 The global name of the threadpool.
 If empty, then the threadpool is made and used according to the scope it's
 in - e.g., for a session threadpool, it is used by that session only.
 If non-empty, then:
 - a global threadpool associated with this name is looked
   up or created. This allows, for example, sharing one threadpool across
   many sessions (e.g., like the default behavior, if
   inter_op_parallelism_threads is not configured), but still partitioning
   into a large and small pool.
 - if the threadpool for this global_name already exists, then it is an
   error if the existing pool was created using a different num_threads
   value as is specified on this call.
 - threadpools created this way are never garbage collected.

 The number of threads in the pool.
 0 means the system picks a value based on where this option proto is used
 (see the declaration of the specific field for more info).
