Without waiting for the local/host routes to be added
by the kernel after the IP address is being added to
an interface. The routes requiring the local/host routes
may failed. This caused flaky e2e tests, but could also
happen during the execution of the VRF plugin when the
IPv6 addresses were being re-added to the interface and
when the route were being moved to the VRF table.
