upstream ci: Add support for testing ipaserver deployment

This patch provides the base for testing ipaserver role using Azure's
infrastructure.

By using containers prepared to thave FreeIPA installed, but
unconfigured, allows the use of a test matrix to test the behavior of
modules in differnt IPA configurations. It also improves tests by
allowing the creation of a test matrix of FreeIPA deployment.

A new pipeline script is provided, which can be used as a standalone
pipeline, os as part of an existing pipeline.

The script 'tests/server_role/inventory.py' is used to create inventory
files for the tests, which should be executed using the existing
'install-server.yml' playbook.

More information on how to generate different inventories can be found
in the accompanying README file 'tests/server_role/README.md'.
