Include terminology definition from docstring

[OpenStack Infra]

Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/watcher" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Include terminology definition from docstring

    As of now, the glossary defined in our documentation reflects the
    current state of the codebase. In order to avoid any discrepancy
    between the codebase and each definition, the objective here is to
    gather both in a single place and link it into the rst documentation
    via a custom directive.
    Also re-aligned the requirements with liberty for doc.

We need to update the glossary to use the new directive here
