Drop centos 8 stream testing

In Zed cycle testing runtime, we are targetting the centos 9 stream
- https://governance.openstack.org/tc/reference/runtimes/zed.html

With dropping the python 3.6 support, project started adding python 3.8
as minimum, example nova:
- https://github.com/openstack/nova/blob/56b5aed08c6a3ed81b78dc216f0165ebfe3c3350/setup.cfg#L13

with that, centos 8 stream job is failing 100%
- https://zuul.openstack.org/build/970d029dc96742c3aa0f6932a35e97cf
- https://zuul.openstack.org/builds?job_name=devstack-platform-centos-8-stream&skip=0

This commit drops centos-8-stream testing so that we focus on centos-9-stream.
