Add unit test for watcher/doc.py

[Jean-Emile DARTOIS]

Although the "Include terminology definition from docstring" pathset got merged https://review.openstack.org/#/c/256419/ we discovered that the class watcher/doc.py has no unit test.

[Vincent Françoise (vincent-francoise)]

The difficulty with this ticket is that the doc generation is not currently possible in python 3.4 which means that adding tests on it will make the py34 gate to fail. So just like other projects did (see nova with https://github.com/openstack/nova/blob/master/tox.ini#L49), we have to skip these unit tests in python 3.4

[Digambar (digambarpatil15)]

Doc-related directives in nova, they do not provide any test for them, we have to move it out of watcher package and put it in the doc/ folder.
We will follow path what nova has taken.

    Moved Watcher doc plugin outside main package

    In this changeset, I renamed watcher/doc.py file as
    doc/ext/term.py which subsequently does not get scanned for coverage
    anymore. Hence, we can close this bug.
