This update adds package google-compute-engine-init to the distribution.

The google-compute-engine-init package provides the initialization code for instances
in Google Compute Engine. It obsoletes packages gcimagebundle, google-daemon and
google-startup-scripts. The code previously provided by gcimagebundle is not replaced.
New image creation from running instances is accomplished using functionality from
google-cloud-sdk or through the GCE web console.

It contains the following tracked changes:

- Scripts that are one-shot should not be marked as "stop_on_removal" as there is no process running. (bsc#1017395)
- Add and improved support for alias IPs in the IP forwarding daemon. (bsc#1016372, bsc#1015829)
- Fix startup script to run after network setup.
- Provide a service to enable network interfaces on boot.
