Bastian Köcher 76d3814e90 Make on_slot return the block with the post header (#8188)
* Make `on_slot` return the block with the post header

Before this pr `on_slot` returned the pre block. However this is wrong,
because adding some post digest changes the hash of the header. Thus,
we need to make sure to return the correct block that uses the post
header.

* Update primitives/consensus/common/src/block_import.rs

* Ensure we spawn the block import worker as an essential task

This pr ensures that we spawn the block import worker as an essential
task. This is quite important as we need to bring down the node when the
block import is done. Besides that it adds some debug output to the
block import worker.

* Fix tracing spans are not being forwarded to spawned task (#8009)

* Fix tracing spans are not being forwarded to spawned task

There is a bug that tracing spans are not forwarded to spawned task. The
problem was that only the telemetry span was forwarded. The solution to
this is to use the tracing provided `in_current_span` to capture the
current active span and pass the telemetry span explictely. We will now
always enter the span when the future is polled. This is essentially the
same strategy as tracing is doing with its `Instrumented`, but now
extended for our use case with having multiple spans active.

Sentry nodes are deprecated. Thus there is no need for

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.

- sudo docker-compose -f .maintain/local-docker-test-network/docker-compose.yml up

* client/network/light: Handle oneshot cancellation

* client/network/light: Do not reduce retry count on missing peer

* client/network: Report reputation changes via response

Allow request response protocol handlers to issue reputation changes, by
sending them back along with the response payload.

* client/network: Remove resolved TODOs

Max Inden b692954c6e client/network: Report reputation changes via response (#7958)
* 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

Max Inden 62d551a063 client/network/req-resp: Prevent request id collision (#7957)
* 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
