So - for a current swag:
- I'm thinking of timing the 'test instance' run (sfw_test_instance_t) -
this would get timing for each test run end-to-end but be detailed
enough to show the different timing with --concurrency > 1 is used.
Doing per-RPC timing seemed to heavy and I'm not sure that level of
resolution is really needed.
- the new command 'test_stat' would collect this data ala the current
'stat' but allow CSV dumping for more fine-grained analysis. I'd
probably dump some node & group info as well to make easier to do
'group' stats.
