John Wren Kennedy 93491c4bb9 OpenZFS 9082 - Add ZFS performance test targeting ZIL latency
This adds a new test to measure ZIL performance.

- Adds the ability to induce IO delays with zinject
- Adds a new variable (PERF_NTHREADS_PER_FS) to allow fio threads to
  be distributed to individual file systems as opposed to all IO going
  to one, as happens elsewhere.
- Refactoring of do_fio_run
