// Key for enabling shrinkages of user listed device memory arenas.
// Expects a list of semi-colon separated key value pairs separated by colon in the following format:
// "device_0:device_id_0;device_1:device_id_1"
// No white-spaces allowed in the provided list string.
// Currently, the only supported devices are : "cpu", "gpu" (case sensitive).
// If "cpu" is included in the list, DisableCpuMemArena() API must not be called (i.e.) arena for cpu should be enabled.
// Example usage: "cpu:0;gpu:0" (or) "gpu:0"
// By default, the value for this key is empty (i.e.) no memory arenas are shrunk
