Setup for syncing of glossary

These files are used by an infra script to sync files from
openstack-manuals to security-doc and operations-guide repositories.

The file projects-to-sync.txt contains a list of repositories to update
and sync-projects.sh handles the copying of files. This is a very simple
script to get the job done.
