charm tries to install lbaas instead of lbaasv2 @ newton when ODL plugin is active

With the ODL plugin, charm tries to install lbaas instead of lbaasv2 @ newton; neutron-gateway install hook fails with unmet package dependencies. I believe get_packages() modifications are necessary to resolve this.
