It would be nice if we would allow docker users to configure this feature, can you add these settings to extras/docker/development/settings.py ? I'd use the same name for the environmental variables

AXES_ENABLED = True -> allow to disable axes entirely (e.g. if this is run in a local network or so we would save up some resources), but default it true
AXES_FAILURE_LIMIT = 5 -> configurable, default is 5
AXES_COOLOFF_TIME = 0.5 -> configurable, default is 0.5
AXES_HANDLER = 'axes.handlers.cache.AxesCacheHandler -> configurable, but default is the cache handler

Just these settings or all the settings related to axes ???

I'd say only these, the others can stay the same for all Installations
