* Disable too-many-ancestors pylint check.
This check was only enabled for ansible-test code.
In some cases this check counts 1 more ancestor in python 3.7+ than under python 3.6, making the check inconsistent and unsuitable for use in ansible-test.
* Disable additional pylint checks:
- import-error
- no-name-in-module
These checks were only enabled for ansible-test code.
These checks provide inconsistent results since they are dependent on available imports, which vary between environments.
It may be practical to enable these checks in the future if changes are made to ensure a consistent test environment for pylint.
