Jakob Meng 1b38b7c500 Properly documented openstacksdk version requirements
With "extends_documentation_fragment: ['openstack.cloud.openstack']"
it is not necessary to list required Python libraries in section
'requirements' of DOCUMENTATION docstring in modules. Ansible will
merge requirements from doc fragments and DOCUMENTATION docstring
which previously resulted in duplicates such as in server module [0]:

* openstacksdk
* openstacksdk >= 0.36, < 0.99.0
* python >= 3.6

When removing the 'requirements' section from server module, then
Ansible will list openstacksdk once only:

* openstacksdk >= 0.36, < 0.99.0
* python >= 3.6

To see what documentation Ansible will produce for server module run:

  ansible-doc --type module openstack.cloud.server

[0] https://docs.ansible.com/ansible/latest/collections/openstack/\
