* Decrease the peer reputation on invalid block requests
This pr changes the block request handler to decrease the reputation of
peers when they send the same request multiple times or they send us an
invalid block request.
* Review feedback
* Change log target
* Remove unused code
* Add a `send_request` to `NetworkService`.
This function delivers responses via a provided sender and also allows
for sending requests to currently not connected peers.
* Document caveats of send_request better.
* Fix compilation in certain cases.
* Update docs + introduce IfDisconnected enum
for more readable function calls.
* Doc fix.
* Rename send_request to detached_request.
* Whitespace fix - arrrgh
* Update client/network/src/service.rs

Sentry nodes are deprecated. Thus there is no need for
`.maintain/sentry-node` to spin up a sentry node test environment.
Instead this commit rewrites the setup to contain two full-connected
validators and one light client.
With the steps below one can now spin up a local test network with
two validators, one light-client, Prometheus and Grafana.

* client/network: Remove resolved TODOs
* Sync: Fix issue of not freeing a block announcement slot
There was a bug that when the block announcement validation returned an
error, the slot reserved for this validation wasn't freed. This could
lead to a situation where we rejected any block announcement from such a
peer for that the block announcement returned an error multiple times.
* Better logging
* Fuck I'm dumb

* client/network: Report reputation changes via response
When handling a request by a remote peer in a request response handler,
one might want to in- or de-crease the reputation of the peer. E.g. one
might want to decrease the reputation slightly for each request, given
that it forces the local node to do work, or one might want to issue a
larger reputation change due to a malformed request by the remote peer.
Instead of having to pass a peerset handle to each request response
handler, this commit suggests to allow handlers to isssue reputation
changes via the provided `pending_response` `oneshot` channel.
A reputation change issued by a request response handler via the
`pending_response` channel is received by the
`RequestResponsesBehaviour` which passes the reputation change up as an
event to eventually be send to a peerset via a peerset handle.
* client/network/req-resp: Use Vec::new instead of None::<Vec<_>>
* client/network: Rename Response to OutgoingResponse
Given that a request-response request is not called `Request` but
`InomingRequest`, rename a request-response response to
`OutgoingResponse`.
* client/finality-grandpa-warp: Send empty rep change via response
* client/network/req-resp: Add unit test for request id collision
* client/network/req-resp: Prevent request id collision
`RequestId` is a monotonically increasing integer, starting at
`1`. A `RequestId` is unique for a single `RequestResponse`
behaviour, but not across multiple `RequestResponse` behaviours. Thus
when handling `RequestId` in the context of multiple
`RequestResponse` behaviours, one needs to couple the protocol name
with the `RequestId` to get a unique request identifier.
This commit ensures that pending requests (`pending_requests`) and
pending responses (`pending_response_arrival_time`) are tracked both by
their protocol name and `RequestId`.
* client/network/req-resp: Remove unused import
* client/network/req-resp: Introduce ProtocolRequestId struct
* client/network/req-resp: Update test doc comment
Treat `RequestId` as an opaque type.
* client/network/req-resp: Improve expect proof
* Sync: Propagate block announcement data
This pr adds a feature to the sync protocol to propagate the data that
we received alongside a block announcement. This is done by adding a
cache that caches the last X block announcement data where X is set to
the number of `in_peers` (giving every peer the chance to send us a
different block). This will be required by parachains to ensure that
even peers who are not connected to a collator receive the data
alongside the block announcement to properly validate it and request the
block.
* Review comment
* Bring back the code and add new variant to ensure we don't insert block
announce data when something wasn't checked

* client/network: Consistently track request arrival time
With https://github.com/libp2p/rust-libp2p/pull/1886/ one is guaranteed
to receive either a `ResponseSent` or a `InboundFailure` event for each
received inbound request via `RequestResponseEvent::Message`. Given this
guarantee there is no need to track arrival times in a best-effort
manner and thus there is no need to use a LRU cache for arrival times.
* client/offchain: Adjust to PeerId API changes
* Update common block in sync after importing blocks of a peer
This updates the sync code to update the common block of a peer, after
we have imported blocks from this peer. This fixes a bug for when we are
connected to one or more nodes that are doing a full sync as our node.
Nodes in full sync will not announce new blocks, as we don't send import
notifications on full sync. The problem as now that we were connected to
some peer that reported some low number as its best and we tried to sync
these blocks. But, as we did not update the common block of this peer,
we would sync these blocks over and over again. Being captured in some
time warp.
The solution to this problem is that we increase the common number as we
import blocks from this peer.
* Test
* Test name..
* Fix test
* Cleanup some code and write some new regression test
* Implement the ancestor search
* Check that the common number is smaller than the last finalized block
