Thanks @enixon for doing the update and rebase, went through this again,
looks legit to me. I also compared with internal version and made sure this has
included all the improvement and bug fixes.
Maybe consider to add the om_proposal_process_time_ms and
om_commit_process_time_ms metric, but this is not a must have.
+1 this should be ready to go.---
