[luisfelipec95]

Description

This PR adds support for the Open edx Palm release. Adds issue templates.

Testing instructions

1. Create an environment with Palm release, you can use Tutor or TVM
2. Install the Django plugin eox-tagging, you can use steps in Tutor documentation.
3. Run test cases

To solve the unit tests, we fix four things:

• We tag pylint to the same version of the edx-platform to avoid errors with directories.
• We tag newrelic with the edx-platform version.
• We use assert_called_once_with.
• We use filterset_class because filter_class was deleted in version 22.1 of django-filters.

Thanks for this, @luisfelipec95. I left you some comments to improve, but this looks good so far.

[MaferMazu]

I updated the readme only because django-filters renamed their functions and could break the functionality in previous versions.

Thanks @luisfelipec95.

This PR looks good.

The test cases are working.
The tests are passing.
The requirements are updated.
And it works.
