* 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`.

* mem usage cleanups for pubsub (#564)
In `async` functions, a closure environment is created for variables
that cross an await boundary - this closure environment is kept in
memory for the lifetime of the associated future - this means that
although _some_ variables are no longer used, they still take up memory
for a long time.
In Nimbus, message validation is processed in batches meaning the future
of an incoming gossip message stays around for quite a while - this
leads to memory consumption peaks of 100-200 mb when there are many
attestations in the pipeline.
To avoid excessive memory usage, it's generally better to move non-async
code into proc's such that the variables therein can be released earlier
- this includes the many hidden variables introduced by macro and
template expansion (ie chronicles that does expensive exception
handling)
* move seen table salt to floodsub, use there as well

ignore)
* `readOnce` avoids `readExactly` overhead for single-byte read
* genericAssign -> assign2
* More gossip coverage (#553)
* add floodPublish test
* test delivery via control Iwant/have mechanics
