[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).
