Update ansible-test default containers. (#69819)
* Move ansible-test completion code.

* Fix a few type hints.

* Change docker completion based on context.

Collections now use version 2.0 of the default-test-container.
This is an updated version of the earlier 1.x default-test-container with ansible-base and cloud specific requirements removed.

Testing of ansible-base now uses version 1.0 of a new ansible-base-test-container.
This container is similar to the earlier 1.x default-test-container, but with unnecessary duplication of requirements across Python versions removed.

Collections which have tests that depend on requirements no longer present in the default test container should specify them in their test requirements files:

* tests/integration/requirements.txt
* tests/unit/requirements.txt

* Bump test container versions
