Enhancing scenario_simulator_v2 to print or visualize parameters/modifiers used for test iterations

[ahmeddesokyebrahim]

Is your feature request related to a problem? Please describe.
While debugging scenarios with different values (list) for modifiers, it is not clear which values is selected and used between different combinations in a specific test iteration.

For example, a scenario with modifiers like that ...

    - name: __tier4_modifier_an
      list:
        - 0.2
        - 2
    - name: __tier4_modifier_D
      list:
        - 5
        - 10

it becomes confusing which value of __tier4_modifier_an is used with which value of __tier4_modifier_D in an iteration.

Describe the solution you'd like
It will be helpful if the parameters and modifiers used for each iteration is visualized in RViz.

Describe alternatives you've considered
It could a valid alternative to have it only printed in the terminal instead of text visualization in RViz

@yamacir-kit Do you have any opinion about how these information should be output to the user? (in Rviz, in terminal, make the verbosity configurable, etc.)
