With Ansible OpenStack collection 2.0.0 we break backward
compatibility to older releases, mainly due to breaking changes
coming with openstacksdk >=0.99.0. For example, results will change
for most Ansible modules in this collection.
We take this opportunity to drop the symbolic links with prefix
os_ in plugins/modules and the plugin routing in meta/runtime.yml.
This means users have to call modules of the Ansible OpenStack
collection using their FQCN (Fully Qualified Collection Name) such
as openstack.cloud.server. Short module names such as os_server
will now raise an Ansible error. This also decreases the likelihood
of incompatible Ansible code going undetected.
Symbolic links were introduced to keep our collection backward
compatible to user code which was written for old(er) Ansible releases
which did not have support for collections and where OpenStack modules
where named with a prefix os_ such as os_server which is nowadays
known and stored as openstack.cloud.server.
In Ansible aka ansible-base 2.10, a internal routing table
lib/ansible/config/ansible_builtin_runtime.yml [1] was introduced which
Ansible uses to resolve deprecated module names missing the FQCN (Fully
Qualified Collection Name). Additionally, collections can define their
own plugin routing table in meta/runtime.yml [2] which we did.
In ansible-base 2.10 and ansible-core 2.11 or later, if a user uses a
short module name and the collections keyword is not used, Ansible
will first look in the internal routing table, get an FQCN, and then
looks in the collection for that FQCN. If there is another routing
entry for that new name in that collection's meta/runtime.yml,
Ansible will continue with that redirect. If it does not find another
redirect, Ansible will look for the plugin itself, so it will not
find a redirect in the collection before looking at its internal
redirects. Except if the user uses a FQCN, then it looks directly in
that collection.
Ansible 2.9 and 2.8 do not have any notion of these redirects with a
plugin routing table, backward compatibility with deprecated os_*
module names is solely achieved with symbolic links. Ansible releases
older than 2.11 are EOL [3], so usage of os_* symlinks should reduce
soon.

We don't use github, so having @ mentions of specific humans is
not valuable. Also, we are a team and own the modules as a team,
so calling out individual authors is philosophically contrary.
We landed a patch upstream to special-case this author string.

don't inherit OpenstackModule class from AnsibleModule class to
prevent occasional overriding Ansible methods or vars and failing
module.

This is separate from the previous patch - it's just the results
of running the script so we can review the two a little independently.
We should probably squash them.
