Update or replace jsonfield

[Jawayria]

We use the package jsonfield in edx/course-discovery. It hasn't yet added support for Django3.2. Please follow the guidance in https://openedx.atlassian.net/wiki/spaces/AC/pages/3036972032/Handling+Outdated+Dependencies to resolve the problem this poses for the Open edX Django 3.2 upgrade.

I saw that someone was trying to run tests for this package with Django 3.2 and the tests failed. I think I can correct it or find another alternative. I will be working on this.

@MaferMazu Thank you for reaching out, I highly appreciate your interest and help with this. I have assigned this task to you. Please feel free to open a PR once you are ready, I will take care of it from there on.

I think the jsonfield library supports django 3.2, the only thing missing is that the author approves some PRs to add the corresponding tests. I already wrote to the author and the maintainer and created an issue rpkilby/jsonfield#264

I took the tests that are in the PRs

@MaferMazu Thank you, I hope you hear back from them soon. Please keep us posted here.

jsonfield allows to use JSONField but Django>=3.1 includes JSONField (models.JSONField and forms.JSONField)
https://docs.djangoproject.com/en/3.2/releases/3.1/#jsonfield-for-all-supported-database-backends
and in edx/course-discovery jsonfield is only used in the requirements, so I think this package could be removed.

We'll shortly have a few other usages of this package as we migrate over from jsonfield2 as explained in #34 . And it would be tricky to jump directly to Django 3.1+ JSONField as I noted in #34 (comment) .

[MaferMazu]

This issue would be resolved equal to #34 which is already closed.

Agreed, closing it as we have an upgrade path now. Thanks for helping sort this out! Tl;dr for those following up on this issue later: we believe the latest PyPI release of jsonfield should work with Django 3.2.
