Save bench parameters in the summary of the bench result

[benoitgillet]

Is your feature request related to a problem? Please describe.
When i use the benchmark feature, everything work as expected.
However, the settings of the bench are not saved in the result file. So for exemple if i change the URL, or the number of request for a container, i lost the information about the settings of the bench that have already run

Describe the solution you'd like
URL, number of containers and number of requests could be added to the summary in the bench result
Theses infos could also be added in the optional columns that would be activated in the views.yaml file.
