#34950 Cleanup nano refetch commands in the background (#42472)
<!-- Add the related story/sub-task/bug number, like Resolves #123, or

**Related issue:** Resolves #34950

I changed from the original spec of 100 old commands to 3 due to load
test results. Admittedly my load test meant a very large number of hosts
all checked in and triggered deletion at once but at 100 per host and
per command the load was too high. 3 still results in cleanup over time
and doesn't seem to cause load issues.
