Output all triggers on app startup

[kate-goldenring]

Right now, the shim only logs the HTTP endpoints available at startup. Ideally it would log information about other triggers that are available. Take for example an app that has 2 HTTP triggered components and 1 mqtt triggered component, the output is simply:

Serving http://0.0.0.0:80
Available Routes:
  api: http://0.0.0.0:80/api
  frontend: http://0.0.0.0:80 (wildcard)

It would be nice to also have information about the other triggers
