Fixes certificate generation error for Neutron agents

TLS certificates were introduced for the Neutron Base service in order
for Neutron to securely communicate with OVS via SSL/TLS.  However, the
implementation only required Neutron DHCP agent (ODL deployment) to use
the certificates.  The other OVS agents are not used in ODL deployments
and SSL/TLS use there may be added in the future.  However, since other
services inherit NeutronBase config_settings, they will attempt to
generate certs.  This certificate generation will fail because these
services do not inherit metadata settings.

This patch fixes the above issue by adding the metadata settings
inheritance to every service derived from NeutronBase.
