DFP QoS work and DFDally Custom Standalone model
This merge request contains the changes for Dragonfly Plus model relating to the QoS features
Additionally, the "custom" dfdally standalone model is added as well. In development of the 1D dragonfly model for the needs of QoS, the model diverged enough away from dragonfly-custom.C and for the time being has been put into a standalone model temporarily. This will eventually be reintegrated with dragonfly-custom.C or will replace dragonfly.C entirely.
Note: incast SWM workload stuff has been commented out in comm-online-workload.c as it prevented compilation with some SWM versions. Feel free to uncomment it prior/post merge.
