Subject: 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.
