Subject: [PATCH] Add HTTPS server

Configuration example:
```
"http_server": {
  "type": "https",
  "port": 8891,
  "cert": "/path/to/fullchain.pem",
  "key": "/path/to/privkey.pem"
}
```
type: "http" | "https" (default: "http")
port: (default 8282)
cert: path to server certificate
key : path to private key

If "http_server" key is missing, no HTTP server will be started.
If "type" == "https" && ("cert" || "key" is missing or corrupted)
an error will be thrown.
