UUID mismatch on newer cloud-init

[Matthew Edmonds]

The version of cloud-init in Ubuntu 18.04 is much newer than that in other distros. When the newer version processes an instance to determine if it is first boot or not, it compares the config drive UUID with the VM UUID. We need to make those values the same for a given VM / config drive pair.

This was already addressed in the master branch with https://github.com/openstack/nova-powervm/commit/5d438733eb310b278d44aada7340a56ee9325063 but we also need to address on any stable branch that may be used with newer cloud-init versions.

    Sanitize the config drive UUID

    When cloud-init processes an instance to determine
    if it is first boot or not, it compares the config
    drive UUID with the VM UUID. This change makes those
    values the same now for a given VM / config drive pair.
