This issue tracks reimplementation of the work from stale PR #2754, which is being closed because it is too out of date to merge directly.
Original PR: https://github.com/clockworklabs/SpacetimeDB/pull/2754
Original author: @gefjon
Original branch: `phoebe/metric-client-queue-length`
Base branch: `master`
## Original PR summary
# Description of Changes
This PR adds two new metrics, spacetime_client_connection_incoming_queue_length and spacetime_client_connection_outgoing_queue_length, which track the lengths of the per-client incoming and outgoing message queues. We expect to use these metrics in testing, incl. bot testing, but not to merge them, as we expect the cardinality of per-client metrics to be too high. I will open a separate PR with per-database versions of these metrics which we can merge.
## Follow-up
- Reimplement this change in a fresh PR against current `master`.
- Carry forward any still-relevant context from the original PR discussion and review.
- Link the new implementation PR back to the original stale PR for historical context.
