It leverages the latest change from lfdocs-conf and the
upper-constraints.txt now centralized in ONAP docs.
In a long run, upperconstraints.os.txt should be removed once ONAP
is synced with OpenStack.
It removes tox and setuptools from requirements as nothing depends on them
(most requirements should be removed except lfdocsconf)
