Enable "kernel_engine" option for Kernel Initiator
class to enable ability to use io_uring engine on
initiator side.
For NVMe-oF this has limitations as apparently it's
not possible to enable polling on the initiator side,
which in turn makes fio "hipri" option also not
possible to use.
Adding #TODO sections with notes in case this is
later fixed in Kernel NVMe driver.
