The following non-security related enhancements/bug fixes are included:

* The Qlustar netboot process has been further improved: We now ship a dedicated C++ based multicast-enabled image pusher 'ql-mcastd' to run on the head-node. This fault-tolerant daemon delivers the assigned OS image of a node to the corresponding client processes running in the further stripped down initial RAM disk (now a mere 25MB). There is a new config file /etc/qlustar/ql-mcastd.conf for this daemon. It is automatically generated correctly when the DHCP config is written. * The nvidia image module is now based on driver version 410.104 supporting the newest GPUs. * Qlustar installer 10.1.1-2 was updated to run on the same kernel version as on the finally installed system. * QluMan has added the possibility to mass import MAC addresses for new hosts from a file. This allows to quickly setup large numbers of compute nodes. * QluMan fixes: - Fix exception when opening Preferences - Don't list initramfs as possible module - HostTemplatesWidget: Don't allow assigning global sets to a host template - EnclosureView: catch KeyError when deleting from Props2Hosts - EnclosureView: Include global template when checking host hardware status - CommandEditor: fix exception when moving command to group - GPU Wizard: Fix open slurm config button
