Delete deprecated argument

[jfalfaro]

Support for context argument was removed in Django 3.0

[vinitkumar]

@heller166 Thanks for contributing, Can you please write this code in a backward compatible way so that it doesn't break for old version of Django and works for the newer versions too?

[jfalfaro]

I'm not sure that I can do that now that. I was trying to avoid getting a RemovedInDjango30Warning that is issued in the following code. The function that is executed to check if context is present checks the method signature and I can't come up with a way for it to be removed while keeping backwards compatibility.

def func_supports_parameter(func, parameter):
    return parameter in inspect.signature(func).parameters

@heller166 You did't had to close your pull request.

Check this code, how we can fix some deprecation warnings or errors using this conditionals, and also this:

from platform import python_version
from django import get_version

from distutils.version import LooseVersion


DJANGO_VERSION = get_version()
PYTHON_VERSION = python_version()

# These means "less than or equal to DJANGO_FOO_BAR"
DJANGO_2_2 = LooseVersion(DJANGO_VERSION) < LooseVersion('3.0')
DJANGO_3_0 = LooseVersion(DJANGO_VERSION) < LooseVersion('3.1')
DJANGO_3_1 = LooseVersion(DJANGO_VERSION) < LooseVersion('3.2')
DJANGO_3_2 = LooseVersion('3.2') <= LooseVersion(DJANGO_VERSION) and  LooseVersion(DJANGO_VERSION) < LooseVersion('3.3')

@vinitkumar thanks for the suggestion. I implemented a solution, let me know what you think. I tried to come up with some way to test this but it seemed a bit more trouble than its worth.
