osd: Add mechanism to avoid running OSD benchmark on every OSD boot-up

Use "mon_cmd_set_config()" to store the OSD's max iops capacity to
the MON store during the first bring-up. Don't run the OSD benchmark
test on subsequent boot-ups if a previously persisted iops capacity is
available on the MON store and is different from the default iops
capacity.

Add the 'force_run_benchmark' flag to force a run of the benchmark
in case the default iops capacity cannot be determined.
