CentOS 8: Add zuul build and publish jobs

Adds build and publishing jobs for CentOS 8 images:

- kolla-build-centos8-binary
- kolla-build-centos8-source
- kolla-publish-centos8-binary
- kolla-publish-centos8-source

The 'base' image has been added to the list of unbuildable images for
CentOS 8 (now separate from the list for CentOS 7). This means that no
images will be built - the jobs should essentially be a 'noop'.

Partially-Implements: blueprint centos-rhel-8
