Subject: Don't emit log for missing attribute check policy
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=3940b430f1e72b70a758d348fb5447f0fb0aa17f;p=openstack-build%2Fneutron-build.git

Don't emit log for missing attribute check policy

A missing policy for validating whether an attribute should
be visible or not is a perfectly normal condition, and
there is no value in logging it.

Writing this information to the log is also having a
considerable performance impact on list operations.
