fix(dev-server): ssl support

[simonhaenisch]

Closes #950, allowing to supply a custom certificate and key and serve the app over https instead of http.

Generate a cert and key using openssl:

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes -subj '/CN=localhost'

Include the following in the Stencil config:

import { readFileSync } from 'fs';
import { Config } from "@stencil/core";

export const config: Config = {
  devServer: {
    https: {
      cert: readFileSync("cert.pem", { encoding: "utf-8" }),
      key: readFileSync("key.pem", { encoding: "utf-8" })
    }
  }
};

(might need to install @types/node for typescript to find the fs module).

Docs update in ionic-team/stencil-site#447.

@simonhaenisch it's worth to add that command for generating pem files in this page https://stenciljs.com/docs/dev-server
