The cue-based configuration allows to specify separate machines for clients and replicas. Further, it allows to specify how many replicas and clients should be placed on those machines. The Go code takes care of assigning replicas and clients to machines based on the number of replicas and clients specified in the config. Furthermore, you may optionally specify locations where the replicas should be placed (and corresponding latencies will be applied by the latency framework). Finally, you may also specify treePositions for the replicas; the treePositions refers to the positions in the locations list, and follow a given format (root, left, right, left-left...) Finally, you may also specify Byzantine strategies of the different replicas in the locations list, by providnig a map from strategy name (slow, silent) to a list of replicas that exhibit this behavior. Please see the schema.cue for specification of constraints, and the code for details on how to use it within the framework.
We don't need to provide a latency file if we are not using the locations field. We currently don't check if locations is provided (so we still allow to provide the latenciesFile even though we don't use it when locations isn't provided.)
This allows to specify also the branch factor to use for a given tree configuration.
We no longer support providing latency file at runtime as part of the config; we instead compile the hotstuff binary with the appropriate latency file. Hence, you should run the latencygen before running with a given configuration. One issue is that the config file may contain location names that don't match the csv latency file.
