drop DynamicRouter::match

This method is redundant to matchRequest but prone to information loss. See discussion in #105. The ChainRouter still has the match() method.

not sure if anybody is using this interface. but it was too restrictive. can we do this? otherwise we would need to keep `match` and throw an exception on dynamic router.

should this go into changelog as well?
