* Docker: drop alpine
Create a multistage docker build image that uses debian to install certs
and then create the final image by using FROM: scratch. This creates a
(slightly) smaller images and drops busybox and alpine.
* Even less copying
* update dockerfile to allow use of https_google
to use TLS in a docker container (based on Alpine linux) you need to also include the CA certificate files
* cleaned up version of Dockerfile that supports https_google
