libvirtd: add parallelShutdown option
This adds a new ``parallelShutdown`` option that allows users to control how many guests can be shut down concurrently. Allowing multiple virtual machines to be shut down at the same time reduces the amount of time it takes to reboot the host. Upstream documentation: https://www.libvirt.org/manpages/libvirt-guests.html#files
