    local_settings.py: Disable django.template DEBUG messages
    
    VariableDoesNotExist error in DEBUG messages from django.template are
    super noisy. It happens even for cases where variables are not defined
    like "default" filter. It also happens with Django built-in templates.
    Previously we tried to fix VariableDoesNotExist errors in our templates,
    but it tunrs out there is no convenient way to prevent it.
    
    We agreed to disable django.template DEBUG messages by default
    in the horizon weekly meeting [1].
