Feature Idea: extend dumpdata command with django-filters

[Diego Margoni]

I recently had the need to dump a huge table using the Django dumpdata command but I only needed a subset of records base on some standard filter.

I think there is already an external package for this, but for basic filtering I think it would be useful to have it integrated in Django simply adding a parameter to dumpdata command..

I would already have a pr ready for this, just wanna know if it might be useful.
