API for the sg-dump script.
 `files` a list of input filenames to be dumped by SgDump
 `output` the name of the output (ASCII) file
 `nevts`  the number of events to dump (default: -1 ie all)
 `skip`   the number of events to skip at the start (default: 0)
 `dump_jobo` switch to store or not the automatically generated jobo (put
             the name of the jobo output name in there if you want to keep
             it)
 `pyalg_cls` the fully qualified name of the PyAthena.Alg class to process the file(s) content (PySgDumper or DataProxyLoader)
 `include`: comma-separates list of type#key container names to dump.
 `exclude`: comma-separated list of glob patterns for keys/types to ignore.
 `do_clean_up` flag to enable the attempt at removing all the files sg-dump
               produces during the course of its execution
 `athena_opts` a space-separated list of athena command-line options (e.g '--perfmon --stdcmalloc --nprocs=-1')
 `conditions_tag` force a specific global conditions tag
 `msg`    a logging.Logger instance

 returns the exit code of the sub-athena process
