Provide best practice / convention for names of parameters

Describe the feature

The mandatory rules for parameter names are now clarified, so that they can be interpreted by a parser.
What we don't have yet is a best practice / convention for the names.

Describe the solution you would like

snake_case / lowercase with underscores between words (e.g. ego_init_speed_mps)

Describe alternatives you have considered

There are different naming conventions in the programming area, e.g. CamelCase, snake_case...

Describe the backwards compatibility

Yes, non-mandatory convention. Old scenarios with different naming convention are still valid.

Additional context

None.
