Rate limit connection

[opieters]

Description

Fix consistency issue: when using async with self.xknx.management.connection, it was not possible to add a rate limit, though the underlying connect function supports this. This PR makes both ways of creating a connection consistent.

I did not add a changelog update, since there's no release yet which supports rate limiting connections.
