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.
Bindep is a binary automation tool used in openstack-infra. With it,
projects can better control the default packages installed into the
OS. Because we are using puppet, we actually don't want any packages
installed by default as to better test our manifests.
