I've committed the 03 patch to master-txnstats branch for now.
I will keep the JIRA open to 
1) Run the tests.
2) Address the feedback on 03 patch.

Please do all future work for transactional stats ON TOP OF master-txnstats branch, in separate
patches. 
The epic patch to run the tests here should be made by diffing master with master-txnstats.

I will periodically merge master to make sure it stays up to date; one can also merge locally
just to produce a patch for tests.
Given that the branch was just created, the 03 patch is good for now for a test run.

The fix version for commits to the branch should be txnstats. We will bulk change it to 4.0/3.1
when we merge the branch.

I'm going to clean up existing jiras and file smaller scope items.

Can you update RB with 03 patch? Just to finish the review and perhaps file some more follow
up jiras.

Also can you make a list of things that are missing? There are some JIRAs remaining as subtasks,
I'm not sure if they are addressed as part of the epic patch or not. I filed some known issue
JIRAs, let me know if there's more.
Or is it just enough to fix the tests and it's good?

tables.
