Do reitit.frontend.controllers support calling other controllers from within a controller?

@ahmed1hsn manually yes, just query the :start or :stop from a controller and invoke it. No helpers currently to auto-wire controllers together.

If Controllers were first-class like mw & interceptors (they should be), one could do this:

(def c1 {:start ...})
(def c2 {:start ...})
(def c3 {:start ...})
(def c12 [c1 c2])

(def routes ["/route" {:controllers [c12 c3]}])

Anyone interested in a PR for making that? Basically copying the expansion protocols from reitit.interceptor.
