This patch adds ansible-core version to 2.11 when evaluating
documentation with ansible-doc-test, so both 2.9 (ansible) and
2.11 (ansible-core) are covered when testing documentation,
along with the latest Ansible version available.
There are common parameters in all modules like ipaadmin_principal and
ipaadmin_password. As this list of common parameters will be extended
soon, there is a need to reduce the code and documentation duplicates.
A ModuleDocFragment is added to provide the module documentation for the
common parameters. This is used in the modules with
extends_documentation_fragment.
ansible_freeipa_module has additional ipamodule_base_spec and
get_ipamodule_base_vars. ipamodule_base_spec extends argument_spec in
the module and get_ipamodule_base_vars is used to return a dict
containing the common parameters.
The Github workflow Ubuntu images do not provide Ansible pre-installed
anymore, and this patch forces its installation through Python's pip.
Different jobs were created to test documentation with different
versions of Ansible, currently 2.9 and the latest available.
This change add support for running ansible-doc-test on every
commit or PR, ensuring that roles and modules are able to produce
correct documentation with ansible-doc.
