[RFC] Support for HTTPS Protocol

We need to be able to define HTTPS bindings for our app's deployed with KUDU, so since I found https://github.com/projectkudu/kudu/issues/923 and that didn't seem to have much traction, I thought I would look into how this could possibly be added.

So this is a work in progress, but I wanted to see if I could get some feedback midway as I choose to change the configuration concept as well.

I am still figuring out how to deal wit certificates, as those become a thing to deal with when we suddenly wan't to do https.
We have to, otherwise the IIS won't respond as we have the port in there explicitly. It might be a good option to prioritize http over https in this case if there is any.
