Refactorizations

- INTERNAL_BUILDER: swaps the builder supplied in the env var with the one executed in the container
- BUILDER_VERBOSE: enable verbose mode
- SHARE_WORKSPACE: enable sharing of the build directory with the container
- PRE_SCRIPT/POST_SCRIPT: absolute paths of scripts that have to be executed in the container
