Title: Add retry loop for getting dhcp port

* There is a possible condition (exposed by test_network_basic_ops) where
the subnet will not yet have a dhcp port attached to it, but an attempt
to add a metadata route using the dhcp port will happen. This is resolved
by putting in a couple of retries to give time for the dhcp_agent to create
a port.
