Add new settings attr AUDITLOG_REGISTRY to allow custom auditlogs

[hoangquochung1110]

This PR is to close #617

I've added a new configuration AUDITLOG_REGISTRY, paths to custom auditlog instances
which allow to configure models logging with flexible options (conditionally disabled/enabled logging and custom signal receivers)

Thanks @hoangquochung1110 for the PR.

Honestly, the implementation looks complex to me. I was expecting a simple config that can be used instead of the default auditlog instance and I would suggest to have this for now.

BTW, if you are interested in implementing multiple auditlog instances at the same time, You can have a registry class to map every model to its auditlog instance. you can build the mapping in register method. then you can have multiple auditlog instance at the same time and the instances can be used for models registrations. something like:

from auditlog.registry import auditlog  # default one

custom_auditlog = AuditlogModelRegistry(create=False)

# here in `register` method we have to map the `MyModel` to default auditlog instance
auditlog.register(MyModel)

# here in `register` method we have to map the `MyModel1` to `custom_auditlog`
custom_auditlog.register(MyModel1)

Then in the other places of project, we have to find the auditlog instance based on model

Thanks @hramezani for the review

I realize the implementation looks unnecessarily complex.

My initial goal is to disable signals and define custom signal handlers

I dived into the documentations
and the below snippet of code works for my case:

auditlog.register(
    Model,
)
pre_log.connect(lambda sender, **kwargs: False if sender == Model else True)
post_save.connect(
    receiver=lambda *args, **kwargs: log_create_reverse_fk_to_opportunity(
            action=custom_action, *args, **kwargs,
    ),
    sender=model,
)

I'll close the PR and the issue soon. Thanks

Hello,
I was thinking, if AuditlogModelRegistry was a singleton, could this idea work for multiple instances?
