Description

Restart with Cleanup of a VPC does not update the public-key metadata, it is explicitly set to null in

https://github.com/apache/cloudstack/blob/master/server/src/com/cloud/network/router/CommandSetupHelper.java#L614

Rebooting instances relying on metadata (e.g. coreos) will no longer have the correct public key configured.

Added explanation:
The VPC VR maintains metadata (http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.8/virtual_machines/user-data.html) as static files in /var/www/html/metadata. When a VR is destroyed and recreated (by e.g. "restart with cleanup") this metadata is rebuilt by createVmDataCommandForVMs(). public-keys is missing from that function so it becomes empty after the rebuild and a request for latest/meta-data/public-keys no longer returns the correct key.
