[PATCH 1/6] common/fio: add helpers using io-uring cmd engine

[Luis Chamberlain <mcgrof@kernel.org>]

This will allow us to add tests which use the io-uring cmd engine,
part of fio. They are inspired by the work by Anuj Gupta and
Ankit Kumar which added sample fio files onto fio for this exact
purpose.

We can build on those to expand test coverage with elaborate tests.

We don't specify the cmd to allow other types of io-uring cmd
users to use this other than nvme.
