Allow for alternative fio job layout.
"group" (default) will create X fio job sections for
X assigned CPUs and distribute available NVMes between
sections. (e.g. 4 CPU test with 24 NVMes will result in
4 fio job sections with 6 NVMes each and scaled iodepth)
"split" will create a separate job section for each
available NVMe, but still pin it to desired CPU thread
using cpus_allowed option.
This allows for alternative way of testing io_uring
which fails to run some cases with fixedbufs=true and
high iodepth values (caused by system-wide default
UIO_MAXIOV=1024).
