mohi-kalantari a60668dc2c Add ipv4 routes for cross vm packets ...

So far, VMs had only /32 ip range for VMs and VMs did not need to route
packets for other entities with ip inside. For Kubernetes CNI,
we will have pods which need to send packets out of the VM to another
destination in the same private subnet. In that case we need to add routes
to the VM's network namespace.

For creating the routes, the code execution is faster than linux
taking care of device creation, so we would wait for at most 0.5 second
to change the routes.

Also some change were made to show the right private ipv4 address based
on the VM's ipv4 netmask. If the netmask is /32, that ip is returned but
in the case of bigger ranges (anything bigger than /32) we will return
the nth(1) ip of the range and reserve the first one for the gateway
