Closes: #2405.
- When Django module is mocked, there are some cases where modules using django
can't be imported due to errors.
- To fix that, don't mock the django module and require django and related
Debian packages to be installed on the system generate developer documentation.
- Initialize django in Sphinx configuration to allow django modules to be
imported without errors.
