docs: Searches through the given apps to find the named command class. Skips
      over any packages specified by exclude_packages and any command class
      specified by exclude_command_class. Returns the last command class found
      or None if the command class could not be found.
      
      Django's command searching behavior is backwards with respect to other
      features like template and static file loaders. This function follows
      that convention.
