Removes the bespoke rcmgr metrics with the default libp2p metrics. This allows us to use the libp2p-maintained dashboard on all of our Grafana instances.

It would be great if this could be merged for the v0.21 release. There've been quite a few instances recently where libp2p dashboards have helped us pinpoint a problem. Not having rcmgr metrics has made debugging more complicated than necessary.

Not sure why sharness is failing. Has something to do with Prometheus metrics. I don't have a sharness setup locally, so I won't be able to debug this. I'd also argue (again) that it doesn't make sense to have any test that asserts what metrics downstream libraries are exposing.

This is a nice cleanup.

The sharness was failing because we have early warning when exposed metrics change, and this PR introduced diff:

-libp2p_rcmgr_memory_allocations_allowed_total
-libp2p_rcmgr_memory_allocations_blocked_total
-libp2p_rcmgr_peer_blocked_total
-libp2p_rcmgr_peers_allowed_total

Rebased, updated tests and added changelog entry informing people about removal, and that Kubo switched to upstream ones.

Once CI is green, will ship in 0.33.
