There is now a global PeerStore structure (instead of having one for libp2p, one for waku, etc)
The user can create custom books for new types easily
Also add a pruning system to remove dead peers
* gossipsub: adding duplicate arrival metrics
Adding counters for received deduplicated messages and for
duplicates recognized by the seen cache. Note that duplicates that
are not recognized (arrive after seenTTL) are not counted as
duplicates here either.
* gossipsub: adding mcache (message cache for responding IWANT) stats
It is generally assumed that IWANT messages arrive when mcache still
has the message. These stats are to verify this assumption.
* libp2p: adding internal TX queuing stats
Messages are queued in TX before getting written on the stream,
but we have no statistics about these queues. This patch adds
some queue length and queuing time related statistics.
* adding Grafana libp2p dashboard
Adding Grafana dashboard with newly exposed metrics.
* enable libp2p_mplex_metrics in nimble test

* feat: allow msgIdProvider to fail
Closes: #642.
Changes the return type of the msgIdProvider to `Result[MessageID, string]` so that message id generation can fail.
String error type was chosen as this `msgIdProvider` mainly because the failed message id generation drops the message and logs the error provided. Because `msgIdProvider` can be externally provided by library consumers, an enum didn’t make sense and a object seemed to be overkill. Exceptions could have been used as well, however, in this case, Result ergonomics were warranted and prevented wrapping quite a large block of code in try/except.
The `defaultMsgIdProvider` function previously allowed message id generation to fail silently for use in the tests: when seqno or source peerid were not valid, the message id generated was based on a hash of the message data and topic ids. The silent failing was moved to the `defaultMsgIdProvider` used only in the tests so that it could not fail silently in applications.
Unit tests were added for the `defaultMsgIdProvider`.
