Add checks to verifiy if a new build is needed This checks if the source materials (python image, Netbox commit, netbox-docker commit) have changed since the last build. This check is done by comparing the digest and commit ids from the previous image with the given tag to the current values taken from the Git and Docker repositories. The checks are only performed for builds by the automated builds on Github.

Gunicorn is replaced with nginx-unit We now serve Netbox with an nginx-unit instance instead of Gunicorn. This allows us to get rid of the extra Nginx container because Unit is also serving the static files. The static files are now collected at container buildtime instead of every startup.

Checkout the repository with git This changes the build process even further. Instead f using `wget` to fetch the current code, `git` is used. This allows for faster switching between branches, because only the differences between them have to be fetched from the server. But the main advantage is that the build cache can finally be used as designed by Docker. Repetitive builds are very fast now. This is also true between branches and tags, as long as the `requirements.txt` file doesn't change.

Refactor to multistage builds This commit introduces a huge change in the build process. What changed: - Dockerfile.ldap was integrated into Dockerfile as a seperate [build stage][multistage-build]. - All the build scripts were refactored according to this. - The `docker-compose.yml` file was adjusted likewise. - The main build script, `/build.sh`, now always builds all targets (formerly called variants). - The minimal requirements for Docker and docker-compose have increased. - The build on hub.docker.com must be adjusted. This change should also fix #156 permanently. [multistage-build]: https://docs.docker.com/develop/develop-images/multistage-build/
