Adds autobackup (integrated, managed VM backups with automatic remote
filesystem mounting, included backup expiry/removal and automatic
full/incremental selection, independent from the manual "pvc vm backup"
commands) to the CLI client.
This is a bit of a large command to handle only inside the CLI client,
but this was chosen as it's the only real place for it aside from an
external script.
There are several major restrictions on this command, mainly that it
must be run from the primary coordinator using the "local" connection,
and that it must be run as "root".
The command is designed to run in a cron/systemd timer installed by
pvc-ansible when the appropriate group_vars are enabled, and otherwise
not touched.
Adds a new API query parameter to define the file size, which is then
used for the temporary image. This is required for, at least VMDK, files
to work properly in qemu-img convert.
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.
