* core: replace GetMiddleware See the discussion in #881. GetMiddleware would add a `nil` middleware to the callstack thereby breaking functionality. This PR drops it in favor of RegisterHandler which is a completely standalone registry for middleware that want to let it self know to other middleware. Currenly *autopath* uses this to call *kubernetes*'s AutoPath method for dynamic autopathing. * Drop GetMiddleware * Register metrics * drop the panic
