    last ${MAX_BUILDS} builds. It checks the build to delete is not building at that
    moment and it also keeps the builds that are:

        - keepLog (marked as "Keep this build forever")
        - lastStableBuild
        - lastSuccessfulBuild
        - lastSuccessfulBuild
        - lastUnstableBuild
        - lastUnsuccessfulBuild
