GitLab

Yearly copyright update

This way we don't need to install git in the container and we can do
additional cleaning without cramming everything on one line

This way we don't need to combine all the commands into one and purge so
many files

Install the dependencies of *all* eHive versions instead of relying on the ones installed in the base image (which is only the latest version)

The cache is cleaned up if you set EHIVE_SOURCE or GUIHIVE_SOURCEi environment variable before deployment
