Previously, either "--restart" was specified or a prompt was given, with
the prompt being ignored with "--unsafe" in favour of a reboot. This
failed to provide an explicit way to prevent VM restarts with these
commands, which might be desired in some non-interactive situations, and
the interaction of "--unsafe" with this option was an undesired bug.
This is now a complete binary flag with --restart and --no-restart
versions, while still defaulting to a prompt if neither is specified.
This allows full non-interactive control of this option.
It didn't make any sense to me for mem(prov) to be the default selector,
since this has too many caveats versus mem(free). Switch to using
mem(free) as the default (i.e. "mem") and make memprov the alternative.
1. Error out when trying to add a new network to a VM if the network
doesn't exist on the cluster.
2. When showing the VM list, only show invalid networks in red, not the
whole list.
1. Ensure that system_template and script are not nullable in the DB.
2. Ensure that the CLI and API enforce the above and clean up CLI
arguments for profile add.
3. Ensure that, before uploading OVAs, a 'default_ova' provisioning
script is present.
4. Use the 'default_ova' script for new OVA uploads.
5. Ensure that OVA details are properly added to the vm_data dict in the
provisioner vmbuilder.
This is a breakage between the older version of Celery (Deb10) and
newer. The hard removal broke Deb10 instances.
So try that first, and on failure, assume newer Celery format.
