Use official OpenStack Yoga upper constraints

As they remove sphinx from the list, we can switch to the
official files. etc/upper-constraints.os.txt will be
removed once all ONAP part of doc's conf.py are updated.

It also fixes master's and releases's tox.ini and modifies
conf.py to make spellcheck work.

It syncs release/_static/css/ribbon.css which was obsolete.
