[Bug 1350974] Openstack python-watcherclient

[Red Hat Bugzilla]

https://bugzilla.redhat.com/show_bug.cgi?id=1350974

--- Comment #12 from Haïkel Guémar  ---
Package looks much better, but you need to fix:
Version: 0.24.0
Release: 1%{?dist}

Version field holds upstream versioning, Release is spec file versioning, and
you should not redefine upstream_version, as it is used by DLRN.

Requires: sphinx is unneeded.

prefer python-XXX over python2-XXX requires for python2 packages.
