doc: Group connector and processor parameters

[hariso]

Currently, a connector's or processor's own parameters can get mixed with the common SDK parameters, e.g.

It would be good to group them so that we first list a connector's/processor's parameters and then the common parameters.

@hariso you mean, just positioning the ones for the specific connector on top and then the commons below maybe, or something else?

[hariso]

@raulb Exactly, it's just about re-ordering.

The team was talking about sorting the parameters based on whether they are required and then alphabetically.
