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.
