[COST-2231] Upgrade to Django 4 #4844

* Remove gettext alias * Mocks for get_response required by middlewaremixin * Use method_decorator to apply neevr_cache on class method * Method set_context deprecated in DRF 3.12 in favor of requires_context * User Django RedisCache and remove django_redis library

* Update deprecated ‘warn’ method * Remove deprecated test case method * Remove deprecated Series.bool method * Correct docstring and class attribute name * Cleanup file handle * Fix flaky test This assert statement will always fail since the template schema does not yet exists. This test will only pass if another test runs before this test creates the template schema. * Update clone_schema.sql Do not define a custom sequence object since that is no longer required with the move to identity columns. Do not define a custom sequence object since that is no longer required with the move to identity columns. * Avoid unnecessary globals * Add management command to migrate serial ID columns to identity * Update license information Add correct copyright and license information to management command. Create project level licenses to reflect the use of multiple licenses within the project. * Improvements to serial to identity management command Use SQL composition rather than format strings to protect against SQL injection attacks. The risk is quite low, but it’s best to just do the right thing. Reorganize the code to avoid a nested function definiton and an unnecessary global variable that only needed to be local. * Add migration to update clone_schema function --------- Co-authored-by: Sam Doran <[email protected]> Co-authored-by: Michael Skarbek <[email protected]> Co-authored-by: David Nakabaale <[email protected]>

* Clean up unittest test_execute_query_with_group_by_tag_and_limit * Move Window after aggregation in group_by annotation Since the Window is used only to provide row numbers and there is no additional filtering done on the data in the Window, moving it after the ArrayAgg fixes the error encountered in Django 4.2 and returns the same data in the same order. * Check correct log level in test This works in Python 3.9 due to a bug in unittest. * Use test database name from settings instead of hard coding it * Use consistent name for test database * Correct patching in test

Currently we are relying on Django’s internal test setup to add a `test_` prefix to the default database name. This works fine most of the time but it’s better to be explicit.

This prevents tripping up flake8 and the need for an ignore or parenthesis

Handling this exclusively with the migrate_serial_to_identity_columns management command
