EphemeralIPv4Network: Be more explicit when adding default route.
On OpenStack based OVH public cloud, we got DHCP response with
fixed-address 54.36.113.86;
option subnet-mask 255.255.255.255;
option routers 54.36.112.1;
The router clearly is not on the subnet. So 'ip' would fail when
we tried to add the default route.
The solution here is to add an explicit route on that interface
to the router and then add the default route.
Also add 'bgpovs' to the list of 'physical' types for OpenStack
network configuration. That type is used on OVH public cloud.
