Add simplified SciFi LiteCluster Online Monitoring

This MR adds a new, simplified SciFi cluster monitor (FTLiteClusterMonitor) as well as the corresponding TAE version (FTLiteClusterTAEMonitor), which are only designed to be used in the online monitoring. The old monitoring included to many plots and options that are not used for the online monitoring, making it difficult to maintain.

The current monitoring will still be available as an offline analysis tool, and is also further simplified in the MR !3497 (merged).

The ideas for this new setup are summarized in these slides.

The corresponding options file is modified in MooreOnline!479 (merged).
