Can you create a separate ctx := context.Background() here and use it in both places.
Ideally, they say you have to use context.TODO() (because you're not supposed to create background contexts outside of main.go). But I'm not very hung up on that rule.

Done. I squashed it with the previous commit.

It's been busy and exciting in vitess upstream. Some changes that felt worth calling out as they could impact assumptions about behavior: - vitessio#4832 — this adds a timeout that is 3x the `healthCheckInterval` which at which point the tablet will stop reporting as healthy - vitessio#4814 — this changes when command line args are used by vttablet - vitessio#4811 — a planned reparent now sets `super_read_only` - vitessio#4805 — behavior coming back from a failed backup is different **Slack changes** @demmer vitessio#4827 Correct suppress logging for begin...commit in autocommit @rafael vitessio#4824 adds timeouts for all statements @demmer vitessio#4826 adds logging of stack traces as opt-in @demmer vitessio#4819 remove begin/commit logs from autocommit txns @demmer vitessio#4796 improves support for vtexplain for begin/dml/dml/commit txns **Non slack changes** vitessio#4839 Improve behavior with reference table routing & vreplication vitessio#4833 Support query routing given there could be multiple targets for a table vitessio#4832 tablets get new health check behavior (health checks time out) vitessio#4837 refresh bug around row streamer handling creds vitessio#4830 apply a default value to the db_name attribute in local_metadata vitessio#4785 SHOW SCHEMAS aliased to SHOW DATABASES vitessio#4829 add experimental support for split clone & vertical split clone via vreplication vitessio#4822 do not normalize in order by vitessio#4791 Adds vreplication row streaming support vitessio#4814 command line flags now used regardless of management mode vitessio#4811 vttablet sets super_read_only during planned reparent vitessio#4803 xtrabackup testing vitessio#4727 support multiple vttablets running against one mysql instance vitessio#4746 TopoCat can now produce JSON output vitessio#4805 mysqld is now restarted after a failed backup vitessio#4685 macos bootstrap bug vitessio#4874 ZK opts and java land vitessio#4695 Adds support for xtrabackup vitessio#4794 fixes build failures vitessio#4725 changes mysql8.0 start args vitessio#4736 introduce new states to support vreplication vitessio#4788 expands orc error **Docs etc** vitessio#4831 lint vitessio#4827 docs vitessio#4816 const declaration cleanup vitessio#4820 const declaration cleanup vitessio#4825 docs vitessio#4818 docs vitessio#4809 docs vitessio#4812 moves consts around vitessio#4813 docs vitessio#4808 docs vitessio#4800 docs vitessio#4795 docs
