perf/nvmf: add FIO I/O rate limit to the config

Browse Source 
Added 'rate_iops' FIO option to the performance scripts.

This will be used during tests where limiting factor
has to be artifically imposed, rather than come from
the target/initiator system or enviroment.

One case for this are scheduler tests, to limit
each connection and balance the threads accordingly.

- run_num - number of times each workload combination is run.
If more than 1 then final result is the average of all runs.
Optional:

#### Test Combinations
It is possible to specify more than one value for bs, qd and rw parameters.
