Remove secret import from vexxhost
I don't think we want to share secrets across tenants.  I don't think
there are any, but if we had them, I mean :)
- vexxhost/openstack-operator
# Include some projects with job config for cross-tenant
# jobs
- - include: [job, secret, nodeset]
+ - include: [job, nodeset]
projects:
- openstack/devstack
- openstack/tempest
