* Upgrade pylint and deps in ansible-test.
* Enable pylint on Python 3.9.
* Update pylint config.
* Add ignore for vendored six.
* Add ignores for support plugins.
* Fix issue reported by pylint.
* 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.
* Update ansible-test collection inventory handling.
- The `windows-integration` command now supports the `--inventory` option.
- The incomplete support for host_vars and group_vars directories has been removed.
- The incomplete support for an inventory directory has been removed.
- The inventory specified by `--inventory` can now reside outside the install and content roots.
- Using `ansible_ssh_private_key_file` with `--docker` or `--remote` results in a warning about the combination being unsupported and likely to fail.
* Fix config handling.
* Fix payload handling of ssh keys.
* Disable pylint no-self-use rule for ansible-test.
* De-duplicate payload paths.
