Summary: With hgsql.verbose turned on, print useful messages like how many commits the server is syncing, how long the lock was held or waited, to stderr so they are visible to the client. This is useful for the client to understand why the server "hangs" for a couple of seconds, and is useful in tests. As we're here, drop no-flake8 comment. Enable the flag for the hgsql-sync test to verify it. Reviewed By: phillco Differential Revision: D10019937 fbshipit-source-id: 8d304ce5208dbc5b92ed20f69daba02e9040c73f
