Pin sphinx to <2.0.0

The 2.0.0 release introduces a requirement for using
python3.5 but we are running this in python 2.7

(cherry picked from commit d2b1c67d57)

Switch to using stestr

According to Openstack summit session [1] stestr is
maintained project to which all Openstack projects
should migrate.
Let's switch it then.
