network: Sort endpoints by name

Sort endpoints by name to control the order in which they are passed to the VM as the interface name inside the VM depends on the order in which it is passed. Long term we should come up with a more robust approach. Fixes #785 Signed-off-by: Archana Shinde <[email protected]> (cherry picked from commit 8f1b28d)
