Added Dockerfile and docker-compose.yml

This is similar to https://nuserv.uni-muenster.de:8443/jbehrens/sds-status-monitor/
but using the recent httpd Docker image as a base.
Also, the .htaccess of sds-status-monitor uses `Satisfy Any`, which seems
to bypass IP address filtering when no basic authentication is set,
which is therefore left out here.

All configuration  is in docker/custom-httpd.conf, no .htaccess is used.
