1) Update tox configuration
Update the tox configuration to pull in the openstack
upper-constraints.txt when running releasenotes. This will
fix the releasenotes job that is currently failing due to
a new version of sphinx. Additionally this change includes
updates from puppet-modulesync-configs.
2) beaker: stop deploying glance-registry and glance v1 API
The API and services are deprecated and marked as removed for Pike.
