neutron-server waits unnecessarily for metadata service when DHCP is disabled

[Daniel Alvarez]

When a port gets bound to a hypervisor, neutron-server will wait up to 15 seconds until metadata is provisioned before transitioning the port to ACTIVE.

Currently for OVN metadata service, a static route is injected via DHCP to 169.254.169.254 via the metadata port so if DHCP is disabled, neutron-server will always wait until timeout since the metadata service cannot be provisioned.

Until we implement some other way for serving metadata, we're depending on DHCP. Anyways, neutron-server shouldn't wait if the port doesn't belong to any IPv4 subnet with DHCP enabled.
