As per [1], neutron-lib 0.3.0 provides a public add/get API for local validator registration/access. This API is preferred over directly accessing the validators dict module-level attribute that's done today when adding a new validator and in fact direct access to the validators dict is deprecated. This patch changes all neutron's usage of the validators dict to use the public API. Closes-Bug: #1584237 [1] https://review.openstack.org/#/c/324090/ Change-Id: I97680b0a8d88cb753199fce7949cfb24b506a0ff
