Subject: [PATCH] Update Kafka configuration types

According to https://nodejs.org/dist/latest-v8.x/docs/api/tls.html#tls_tls_createsecurecontext_options the `ssl` options `ca`, `key`, and `cert` are all optional. In my case, i need to pass `rejectUnauthorized`, but I can't do so as the backend expects a `key`. Passing an empty string works, but everything becomes redacted in my log because of that.
