Lowered maximum OpenStack SDK version to 0.98.999

Alongside OpenStack SDK 1.0.0 we will release a new collection version
2.0.0 which is compatible to OpenStack SDK 1.x.x series only. Code in
branch stable/1.0.0 will remain compatible to OpenStack SDK 0.x.x
series only. Release candidates for the first major release of
OpenStackSDK 1.x.x will be numbered using 0.99.x versions.

At Ansible OpenStack modules PTG on 2022-04-07 it was decided to raise
an error if one is using a incompatible releases of the OpenStack SDK
with our collection. We decided against showing warnings only because
they can be missed easily and functionality  will be broken but
probably hardly detectable when using the wrong SDK.

This patch caps the maximum required SDK versions to 0.98.999, so
that an error will be raised when users try to use our collection with
an incompatible SDK release, e.g. use code from our stable/1.0.0 branch
with a OpenStack SDK 0.99.x or 1.x.x release.
