test: remove unused files, py26 tests

[richm]

We do not use molecule.

The custom requirements are no longer needed.

Remove py26 requirements - the py26 python dependencies are too old now to maintain

Use ansible-core - much smaller than ansible

📝 Walkthrough

Walkthrough

Removes Python 2.6 support from CI by deleting the python-26 workflow job and dropping py26 from the coverage script's tox environments. Updates the Codecov upload action to v6, replaces ansible with ansible-core in requirements files, removes old Python 2.x dependency pins, and clears legacy molecule and custom requirements content.

Changes

Python 2.6 removal and CI modernization

Layer / File(s)	Summary
Drop py26 CI job and update Codecov action .github/workflows/python-unit-test.yml	Removes the dedicated python-26 job (which ran tests via linux-system-roles/lsr-gh-action-py26) and updates the Codecov upload step to use codecov/codecov-action@v6.
Remove py26 from coverage collection script tests/get_total_coverage.sh	The tox invocation for appending coverage data is changed to run only py27, py36, and py37, dropping py26.
Update requirements: ansible-core and remove legacy pins pytest_extra_requirements.txt, ansible_pytest_extra_requirements.txt, molecule_extra_requirements.txt	Replaces ansible with ansible-core for python_version > "2.6", removes old idna and PyYAML version pins that guarded older Python versions, and clears the contents of molecule_extra_requirements.txt.
