Bug Description

I see this across many units when running "juju debug-log --level INFO":
unit-containerd-1: 18:29:51 ERROR juju.worker.metrics.sender could not remove batch "d258d5da-e5c9-4797-88ed-ffb00d06ae48" from spool: remove /var/lib/juju/metricspool/d258d5da-e5c9-4797-88ed-ffb00d06ae48: no such file or directory

Watching the directory, I do see files end up in /var/lib/juju/metricspool. I don't know if we're trying to delete something 2 times. My guess is the ERROR should be suppressed, as we should be ok if the file is gone when we go to delete it. (and/or fix the code to not delete twice)

This was after deploying 'kubernetes-core' on LXD using juju 2.6.9 and upgrading to juju 2.7rc1, however I don't think this is specific to those versions or charms.

Note that the same hash is often reported 2x, but not always. Also, this was with an HA controller, though the error messages are coming from the individual unit agents.

Maybe this is because of subordinates?

Note that those are 2 subordinates on the same machine. Maybe the primary is dealing with the file, and the two subordinate unit agents are then complaining that they aren't able to.
