Steps to reproduce

Pass undocumented kwargs to a bot method

Expected behaviour

The kwargs should either be passed along to the API or an error should be thrown

Actual behaviour

The kwargs are just ignored

Offline discussion (with @Poolitzer @tsnoam @n5y):

• just ignoring kwargs is not good
• we're not really comfortable with passing method kwargs to the API
• we still need class kwargs (being ignored), so api changes dont immediately break the code

Note that this goes again older decisions, see #733.

Before we go for an implementation, let's hear, what @Eldinnie thinks.
