ipaconfig: Add support for SID related attributes.

Since FreeIPA 4.9.8 the 'config_mod' command has parameters to enable
and configure SIDs, and set the Netbios name.

This patch adds the following parameters to ipaconfig plugin:
    enable_sids: New users and groups automatically get a SID assigned
    add_sids: Add SIDs for existing users and groups
    netbios_name: NetBIOS name of the IPA domain

Both add_sids and netbios_name requires 'enable_sid: yes'.

'enable_sid' and 'netbios_name' are returned when querying IPA
configuration.

'add_sids' always generate SIDs for users and groups, so, muiltiple
executions of the playbook with 'add_sids: yes' will return 'changed',
even if users and groups SIDs are not modified.

A new test playbook is available:

    tests/config/test_config_sid.yml

New examples playbooks are available:

    playbooks/config/change-ipa-domain-netbios-name.yml
    playbooks/config/generate-users-groups-sids.yml
