Custom django-admin commands - __init__.py in directories

[Diego Cerdán <diegocerdan@…>]

Documentation should state that the file init.py is required in the management and commands directories.

​https://docs.djangoproject.com/en/dev/howto/custom-management-commands/

Some people (included me) got confused but luckly is solved in this Stackoverflow question:

The first example includes both __init__.py files. Does it really need special emphasis?

[Aymeric Augustin]

I don't believe these files are required on Python 3. (It may remain a good idea to include them.)

[Tim Graham]

Confirmed they are not required on Python 3.

On Python 2, the error is ImportError: No module named management.commands.mycommand. I think that's a fairly intuitive message to indicate that the modules aren't properly configured.

Reported again in #22974 so I'm going to add some emphasis about this.
