changelog: remove cloudsigma custom cloudinit service configuration

CloudSigma uses a serial port to transfer metadata into a running
instance. Because the service was overwritten with the configuration
"restart" it was possible that the previous instance got interrupted.
This left the serial connection in an non-deterministic state as the
next user would get output from the previous request. The service in
general was not needed as the cloud oem is already set to cloudsigma.

+- Removed custom CloudSigma coreos-cloudinit service configuration since it will be called with the cloudsigma oem anyway. The restart of the service can also cause the serial port to be stuck in an nondeterministic state which breaks future runs.
