* Make the GossipsubRpc debug instance a bit nicer

Basically just don't show empty components to reduce visual noise

* Introduce send_message helper function to avoid repetition of boilerplate

This also serves to have a central place to log or otherwise intercept all
outgoing messages to other peers of the behaviour.

* Simplify the arc removal in poll

And do the corresponding changes to make this work.

implement PX and prune backoff + simplify tests for explicit peers

…ack for grafting to peers after backoff

improved data structure for storing backoffs + slack backoff

allow flood publishing (on by default)

…mnation

implement adaptive gossip dissemination + complete config debug output

…n in builder

implements a configurable minimum number of mesh peers that are outbound

…d hooks + using the score of peers in the behaviour logic

use the score module in the behaviour

Gossip v1.1 opportunistic grafting

…sures

… message for the same peer

…aximum number of processed message ids inside ihaves per peer per heartbeat + cap the number of message ids we send inside an ihave

Implement missing spam protection measures

add workflow that checks fmt for all branches and pull requests in package gossipsub

* Propagate signature verification and peer kinds to behaviour

* Propagate validation errors to the behaviour

* handle peer kind + fix flaky test

* Inform the behaviour of invalid messages

* Correct duplicate cache

* penalize invalid messages

* generalize DuplicateCache to TimeCache + implement minimalistic Entry API + use it for deliveries tracking in scoring module

* fix warnings in test

* remove accidentally added benchmark functions

* Handle peers that do not support the protocol

* remove dbg! calls and add debug logging for peer scoring

* export MessageAcceptance and rename validate_message to report_message_validation_result to also signal that this message should get called in case of invalid messages

* fix double reject_message call

* gossip promises are fulfilled already on receiving the message without validation

* derive debug for MessageAcceptance

* add helper method to get config builder from existing config

* allow adding/changing TopicScoreParams during runtime

* more debug output for messages from self

* fixes incompatibility with anonymous PeerId in lighthouse

* cargo fmt

* more debug output for broken promises
