This patch adds support to horizon for volume type encryption delete. The contents of this patch were originally a part of a combined volume type encryption update and delete patch, (https://review.openstack.org/#/c/72024/) but the delete portion has been moved to this patch since the pieces do not depend on each other. The modifications are made to the Admin Volume Type table, and add the Delete Encryption action to the action column. Unit tests are also included. Change-Id: Ide9109ca22a04b9121bc78eeea26be9ef2adbf97 Implements: blueprint integration-with-cinder-volume-encryption
