[FEATURE] add dedicated `set_runtime_parameters` to `Task`, `Step` and `LLM`

[davidberenstein1957]

Is your feature request related to a problem? Please describe. Currently, it can be difficult to grasp and combine all of the runtime parameters for each component.

Describe the solution you'd like something like

class Magpie:
    def set_runtime_parameters(self, arg_a = 1, arg_b = 2):
        super.set_runtime_parameters({arg_a: arg_a, arg_b: arg_b})

Describe alternatives you've considered go into the docs. Additional context NA.
