When [installing watcher-operator|https://gitlab.cee.redhat.com/rhci-documentation/docs-Red_Hat_Enterprise_Linux_OpenStack_Platform/-/blob/rhoso180-antelope/common/optimize/proc_install-watcher-operator.adoc,] on step 1, we include the namespace on the yaml file, to ensure that it is created on the correct one.

But, when [creating the certificates|https://gitlab.cee.redhat.com/rhci-documentation/docs-Red_Hat_Enterprise_Linux_OpenStack_Platform/-/blob/rhoso180-antelope/common/optimize/proc_deploy-optimize-exist-control-plane.adoc,] step 4, we are not including it and step 5 do not add `-n openstack` to the command, so if you are not in the opestack namespace, the certificate will be created on the default namespace.

We can fix it adding `namespace: openstack` to the certificates yaml file and also in the watcher yaml file to avoid the same error (watcher oc apply of point 7 has the -n openstack parameter, so it is not going to fail, but better having in both files).

This is also valid for upstream docs: https://openstack-k8s-operators.github.io/watcher-operator/#_deploying_the_watcher_service
