[PATCH pve-manager 5/6] ui: qemu: options: add editor for reboot behavior

[Jakob Klocker <j.klocker@proxmox.com>]

The `reboot` option is now a property string with an added `powercycle`
sub-property, so expose both in the VM options panel: one checkbox to
allow reboots at all, and one to stop and start the VM on a
guest-initated reboot instead of resetting it in place, which makes
pending changes take effect.
