The well known service type constants are in neutron_lib.plugins.constants, but for legacy reasons a few still exist and are referenced from neutron_lib.constants that we'd like to remove. This patch switches references over to neutron_lib's plugin constants. Change-Id: I1861448cec303725b30cef8f42029f467f9e03a3
