Add feature: DRF Permission Class

[thubamamba]

When using Django Rest Framework with django-tenant-users, an example of how to ensure that TenantUser.tenants can only access their respective resources.

In this case, the use case is with SimpleJWT like so:

REST_FRAMEWORK = {
    "NON_FIELD_ERRORS_KEY": "errors",
    "DEFAULT_AUTHENTICATION_CLASSES": [
        "rest_framework_simplejwt.authentication.JWTAuthentication",
    ],
    "DEFAULT_PERMISSION_CLASSES": [
        "rest_framework.permissions.IsAuthenticated",
    ],
    "DEFAULT_PAGINATION_CLASS": "rest_framework.pagination.PageNumberPagination",
    "PAGE_SIZE": 10,
}

Did you push the right commit @thubamamba? I'm just seeing a bunch of import re-formatting.

Thanks for ping and PR @thubamamba!

After reviewing it, I think we’re not quite aligned on the scope. The current PR adds a new app for DRF, but the setup is mostly standard DRF boilerplate, and doesn’t incorporate anything specific to django-tenant-users.

What I was envisioning was a more targeted example, like a custom PermissionClass that ensures a TenantUser can only access resources for tenants they belong to, addressing your original issue about users being restricted to their specific tenants.

If you could focus the implementation on that along with documentation, it would better showcase how django-tenant-users integrates with DRF.

Feel free to update the PR with this in mind!
