* univention: add common code for univention corporate server modules
* univention: try import only univention specific libraries
* Code Review with @2-B, slight API changes and refactoring.
* Added module documentation overview, describing the provided functions
* Moved module-global objects into getter functions, so that we don't
need to import possibly-unavailable univention modules at the module level.
* Renamed some exports for improved consistency:
- module_name() -> module_by_name()
- orig_ldap -> ldap_module()
- ldap -> uldap()
Note that this introduces slight API changes from the outside. Instead of
directly accessing module properties, you now have module functions with the
same name. Examples:
- ansible.module_utils.univention.position_base_dn()
- ansible.module_utils.univention.config_registry()
- ansible.module_utils.univention.base_dn()
- ansible.module_utils.univention.config()
* module_utils univention: fix library
* move module_utils from univention to univention_umc, because python import univention fails if library is called univention
* univention_umc: fix intention
* univention: change common code to BSD-2-clause
