[docker][experimental] Split the build
Split the container build into two stages: * builder Builds collectd and containers all the build artifacts * final Containers collectd binary and all the dependencies needed to run. Does not contain build artifacts, which contribute to a very large container size. The main advantage is that the final container is much smaller (~700MB vs 1.2GB).
