/*
 api-history:

 Every time the build dependencies of gluon change, the version
 every container has to be rebuilt. Therefore, we use Jenkins
 labels which intoduce a version number which is documented here.
 As soon, as you properly rebuilt your docker container, you
 can notify lemoer, that you have updated your node.

 - gluon-docker-v1:
   - add shellcheck binary to the build environment
 - gluon-docker-v2:
   - add qemu-testlab testing, requires KVM virtualization support
   - require rsync dependency to be able to build the next branch
 - gluon-vmx
   - splits the qemu testing from the gluon-docker-v2 label to accomodate
     nodes without the vmx cpu flag
