Subject: [PATCH] Add non-isolated network metadata server route

In some images routes may be pre-existing for the 169.254.0.0/16
network which makes the metadata server unreachable. This fix adds a
route to the metadata server IP setting the gateway IP as next hop
that makes the metadata server accessible even if a custom local
route is present.
