Kazoo has moved onto 1.3.1

The 0.9 release is over a year old now and kazoo
has made many small changes and bug fixes that it
would be great to take advantage of.

In order to take advantage of these lets bump
up the version.

allow for NON_STANDARD_REQS override

there are non integrated projects in openstack that use devstack
framework for running jobs. They need a lever in their jobs to
tell the infrastructure that we won't enforce global-requirements
strict compliance on them. We'll still generate a warning so that
they know they are using requirements outside of OpenStack's
accepted list, but it will be non fatal.
