Use IPAAnsibleModule methods and ipamodule_base_docs ducument fragment.

By making IPAAnsibleModule the base class of FreeIPABaseModule, instead
of AnsibleModule, some methods on FreeIPABaseModule can be removed and
suport for commom parameters in modules using the older class can use
the same commom parameters (ipaadmin_principal and ipaadmin_password)
as the other parameters. This will also allow easier deprecation of
FreeIPABaseModule, which is hard to maintain.

To be able to use IPAAnsibleModule as the base class, it was moved
within the file, to position before FreeIPABaseModule declaration.

This patch also modifies IPAAnsibleModule by:

    * removing usage of `self` in methods not requiring it, turning
      the methods into @statimethod;

    * adding comments to all the methods in IPAAnsibleModule, which
      makes it easier to understand what the individual methods do,
      and what their parameters represent.

Use IPAAnsibleModule and ipamodule_base_docs in the templates of
utils/new_module.

ipaadmin_password lines in the examples have been added, ipaadmin_
variables are handled by IPAAnsibleModule, ansible_module.params_get is
used to get the parameters and ansible_module.ipa_connect is used to
simplify the module.

ipamodule+member.py.in is additionally using gen_add_list and
gen_intersection_list to reduce the command calls to the changes only.

This class is an extended version of the Ansible Module that provides
IPA specific methods to simplify module generation.

Simple example:

    from ansible.module_utils.ansible_freeipa_module import \
        IPAAnsibleModule

    def main():
        ansible_module = IPAAnsibleModule(
            argument_spec=dict(
                  name=dict(type="str", aliases=["cn"], default=None),
                  state=dict(type="str", default="present",
                             choices=["present", "absent"]),
            ),
        )

        # Get parameters
        name = ansible_module.params_get("name")
        state = ansible_module.params_get("state")

        # Connect to IPA API
        with ansible_module.ipa_connect():

            # Execute command
            if state == "present":
                ansible_module.ipa_command(["command_add", name, {}])
            else:
                ansible_module.ipa_command(["command_del", name, {}])

        # Done

        ansible_module.exit_json(changed=True)

    if __name__ == "__main__":
        main()

pylint: Upgrade to version 2.10.2.

This PR sets pylint to version 2.10.2 in all linter actions, and
fixes code in plugins so that this version new checks are either
satisfied or ignored if needed.

ipapermission: Add 'new_name' as an alias to 'rename'.

build_containers: build CI container images on Sundays.

tests/trust: Add ipaadmin_password to test playbooks.

Use Ansible fact "os_family" as fallback, when distro is not directly suppported.

When loading variables in all ansible-freeipa roles, it is expected
that a file with these variables is present for each supported Linux
distribution, and then, based on the information about the distribution
provided by Ansible, the correct file is loaded.

Previously, only the facts `distribution` and dinstribution version
related facts were used, which required specific files, or links to
files for distributions in the same "family", which will probably have
the same variables set.

This change adds searching for files based on the `os_family` fact,
allowing distributions that follow the same family rules to be
supported, without any changes to the codebase. It is still possible
that a specific distribution configuration overrides the default
behavior, as `os_family` has lower priority than `distribution`.

For example, distributions on the `RedHat` family, like Oracle Linux,
Alma Linux, and Rocky Linux, work withoutadding new files, or links to
files, to fill the `vars`.
