The requirements files have been mostly copied from sahara.git,
but most of the dependencies are not needed.
Refresh the content of lower-constraints.txt and ensure that
the lower-constraints tox environment considers also the doc
Explicitly depend on the pre-release of Sahara for Stein.
Add few more jobs to avoid breakages, namely:
- add check-requirements and openstack-lower-constraints-jobs;
- replace tempest-plugin-jobs with openstack-python-jobs,
openstack-python35-jobs and openstack-python36-jobs
now that it is possible to depend on sahara.
Updating documentation to reflect what it means to the Sahara project,
and make it build again.
Also cleaning up release notes so we can start fresh.
Most important tempest-plugin-jobs, which looks like openstack-python-jobs
but without the py27 job, which is failing right now (waiting for
the sahara patch which exports the plugin interface).
