syntactic sugar for define/create with default args

[Licenser]

Describe the problem you are trying to solve

When defining an operator and wanting to access the config this needs to be exposed over args as the define statement, while really nice for defaulting this can lead to a lot of boilerplates.

  define operator batch from generic::batch args
    count,
    time
  with
    count = args.count,
    time = args.time
  end;
  create operator batch with count = 42, time = 23;

Describe the solution you'd like

We could remove the boilerplate by adding syntactic sugar that follows the rule:

If a define does not have a args or with the statement, it automatically gets it's args populated with the the available options in with.

Risks

Following risks exist:

1. how to handle it when "not set" for a with element has a meaning, we need to think about it
2. how do we reach for the defaults in with when creating the sugar-args
3. does this impact exportability
