Original Pull Request Body

Code Review

This pull request removes the integration-level memory cache tests and refactors the system-level memcache tests in src/tests/system/tests/test_memcache.py. The refactor introduces several helper functions and leverages pytest parametrization to consolidate test logic for users, groups, and initgroups, improving maintainability. However, a critical issue was found in src/tests/intg/Makefile.am, which contains unresolved merge conflict markers that must be fixed to ensure a valid build.

sssd-2-11 branch CI is in a poor state.
Having green system/c10s and system/f42 is enough here.
