    Add missing cleanup step for new apache images

    A few new images got apache as part of blueprint
    apache-packages-for-apis without a cleaning up. Without this step the
    containers may fail to restart due to runtime files already present.

    This commit fixes it for all images with the exception of heat-base so
    that it can be cleanly backported to stable/ocata.

    It also removes the unused APACHE_DIR variable from freezer-api and
    keystone extend_start.sh script.
