Subject: Only warn about deprecation warnings once
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=f946c7e733c57270283440e1fd701070ebddf9d9;p=openstack-build%2Fcinder-build.git

Only warn about deprecation warnings once

Instead of repeatly emitting data about which
modules are deprecated again and again just warn
about those deprecation once and then never warn
about them again.

This is a good thing to have, and will be needed
as taskflow moves one of its classes used in cinder
to a new and longer-term location and will emit
deprecation about the usage of the old location.
