This commit changes the Dockerfile ot use the multi-stage build and help to get an automated build on Docker. The idea of the multi-stage build is to use the already stable Debian distribution channel to provide up-to-date versions of ZeroTier. The benefit is that it would be possible to automate the image build, either on Docker Hub, Travis or taking advantage of the [docker-library/official-images] infrastructure. This changes follows the best-practices suggested by [docker-library/official-images], such as using a High Availability GPG keyserver, providing a default CMD, allowing "bash" on `docker run` and others. Given that both the builder `debian:stretch` and `alpine:latest` are official messages and have [manifests], this means that this Dockerfile is also multi-platform. This means that this same Dockerfile will pick-up the correct Debian package according to the architecture of the running system during build. With this changes we could try to promote the image to be parte of [docker-library/official-images], and take advantage of automated publishing of multi-architecture images. Others would be able to use `docker run zerotier` and download the latest version appropriate to their system.
