meta-google: gbmc-bridge: GW SRC latch gateway status
We don't want route changes to cause the networkd reloads for flapping
default gateway status. We can assume that once a node has a default
route outside the machine it will always be able to act as a router
until powercycle (we don't dynamically reconfigure network uplinks).
Tested: Subordinate nodes still do not become routes and nodes with
uplinks are still correctly identified as routers. Fewer reloads are
shown in the logs.
