Configurable runner script

[m-fila]

Adding a configurable runner script would be very helpful for development and experimenting with different graphs. Currently there is the examples/schedule that is a go-to script for experiments but it's all hard-coded
A new script could have the following arguments:

• For scheduling:
  • dfg - data-flow graph in GraphML. Should be mandatory argument, it would be nice if this was also a positional argument
  • max-events - total number of events to be processed (currently we have a map of (name, graph) to schedule but we are mostly interested in running the same graph max-events times)
  • slots - number of events that can be processed concurrently (currently MAX_GRAPHS_RUN)
• For tracing:
  • some option to get and save a gantt plot to a given file
  • some option to get and save a chrome trace to a given file (Add render/show_logs to chrome_trace JuliaParallel/Dagger.jl#540, should be available in Dagger 0.18.13)
  • some option to get dot or other format with the graph supposed to be scheduled
  • the same as above for the executed graphs (storing all of them might be a problem with large max-events)
  • option to write the logs to a txt file
• For resources (both can be can be specified in julia so I think there is no need to repeat them in a script arguments):
  • procs
  • threads

It would be great if writing files was followed with some information like @info Written <whatever this file is supposed to be> to <filename>
