CPU usage.

How about making it as a ScopedCleanup, then you don't need to call it manually in every return.

           : participant operations.
Have you ever used multi-row transactions in one of your Kudu clusters?

If talking about TXN participant meta-operations, I'd recommend introducing new metrics based on particular needs and observations from the field, not just blindly adding a metric to fill in the blank spots. 

One source of strange smell in this patch is having an umbrella timings metric for very different types of TXN state transitions.  AFAIK, the timings for FINALIZE_COMMIT and ABORT_TXN might be different order of magnitude compared with BEGIN_TXN due to their nature, and accumulating them under the same umbrella looks like quite a strange idea to me.
