This first commit is adding a first cmdline engine_module to execute a
single fio command line.

This commit is not functional yet but set the base of the logic to parse
the engine.

engines: Rename test_parse to test_parse_stressng
bb49d56 
As new engines are coming, let's name files so it's easy to remember
what file is doing what.

Add Fio support in hwbench #31

@ErwanAliasr1
benchmark: Link parameter with benchmark
0d06c79 
The parameter has no link to the benchmark preventing engines extracting
the benchmark properties including the current job number.

This will be needed by fio to name its jobs.

bench/parameter: Adding get_name_with_position()
3a07a7e 
This function is an helper to provide a unique name to benchmarks.
The current job position is padded to the current job name.

This commit:
- add this new function
- replace the existing occurences.
- change the output to report the name with position at runtime

Before :
[full_cpu_load] stressng/cpu/matrixprod(M): 1 stressor on CPU [0] for 60s
[full_cpu_load] stressng/cpu/matrixprod(M): 2 stressor on CPU [0] for 60s
[full_cpu_load] stressng/cpu/matrixprod(M): 4 stressor on CPU [0] for 60s

After:
[full_cpu_load_0] stressng/cpu/matrixprod(M): 1 stressor on CPU [0] for 60s
[full_cpu_load_1] stressng/cpu/matrixprod(M): 2 stressor on CPU [0] for 60s
[full_cpu_load_2] stressng/cpu/matrixprod(M): 4 stressor on CPU [0] for 60s

hwbench: Adding fio engine
0b065ac 
This commit is adding a first cmdline engine_module to execute a
single fio command line.

This code has been tested on fio-3.19, defining the minimal release
version.

To enable this mode, engine_module must be set to "cmdline".
The expected command line to forward to fio must be provided in the engine_module_parameter_base.

The command line will be tweaked by hwbench to ensure:
- runtime consistency with other engines : --time_based and --runtime are added
- output consistency: --output-format=json+ is added
- job naming: --name is adjusted to match hwbench's job name

Please note that :
- Fio's runtime will inherit automatically from hwbench's runtime value.
- --numjobs value will be fed with 'stressor_range' making possible to
  study the scalability of a device with a minimal code.

If one of these values were already present in the
engine_module_parameter_base, hwbench will replace them by the values
that were computed based on the benchmark descrption.

A sample configuration file (configs/fio.conf) is provided as an example, it will:
- test /dev/sdp in a randread 4k profile
- two benchmarks are automatically created as per the stressor_range
  value ("4,6") :
-- one with numjobs=4
-- one with numjobs=6

The testing suite is added to ensure a proper parsing and benchmarking job creation.
