This update for cloud-init provides the following fixes:

- Properly handle static routes. The EphemeralDHCP context manager did not parse or handle
rfc3442 classless static routes which prevented reading datasource metadata in some
clouds. (bsc#1141969)
- The __str__ implementation no longer delivers the name of the interface, use the "name"
attribute instead to form a proper path in the sysfs tree. (bsc#1144363)
- If no routes are set for a subnet but the subnet has a gateway specified, set the
gateway as the default route for the interface. (bsc#1144881)
