* .maintain: Replace sentry-node with local-docker-test-network

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.

- cargo build --release
- 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/request-response: Assert in debug request id to be unique

* client/network/light: Choose same limit as block request protocol

* 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 f0b99dd2f2 *: Update to libp2p v0.33.0 (#7759)
* *: Update to libp2p v0.33.0

* 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.

Previously this was reported both via a `ResponseFailure::Busy` and a
`ReponseFailure::Network(InboundFailure::Omisssion)` event.

With this commit the former is removed, leaving only the latter in
place.

Max Inden 8fd343e39d client/*: Treat protocol name as str and not [u8] (#6967)
* client/*: Treat protocol name as str and not [u8]

Notification protocol names are in practice always valid utf8 strings.
Instead of treating them as such in the type system, thus far they were
casted to a [u8] at creation time.

With this commit protocol names are instead treated as valid utf8
strings throughout the codebase and passed as `Cow<'static, str>`
instead of `Cow<'static, [u8]>`. Among other things this eliminates the
need for string casting when logging.

* client/network/src/discovery: Adjust to Kademlia  API changes

* client/network: Add peers to DHT only if protocols match

With https://github.com/libp2p/rust-libp2p/pull/1628 rust-libp2p allows
manually controlling which peers are inserted into the routing table.
Instead of adding each peer to the routing table automatically, insert
them only if they support the local nodes protocol id (e.g. `dot`)
retrieved via the `identify` behaviour.

For now this works around
https://github.com/libp2p/rust-libp2p/issues/1611. In the future one
might add more requirements. For example one might try to exclude
light-clients.

Toralf Wittner 51a45c5d9f network: Use "one shot" protocol handler. (#3520)
* network: Use "one shot" protocol handler.

Add two new `NetworkBehaviour`s, one handling remote block requests
and another one to handle light client requests (both local and from
remote). The change is motivated by the desire to use multiple
substreams of a single connection for different protocols. To achieve
this, libp2p's `OneShotHandler` is used as a protocol handler in each
behaviour. It will open a fresh substream for the duration of the
request and close it afterwards. For block requests, we currently only
handle incoming requests from remote and tests are missing. For light
client handling we support incoming requests from remote and also
ported a substantial amount of functionality over from
`light_dispatch.rs` (including several tests). However the result lacks
in at least two aspects:

(1) We require external updates w.r.t. the best block per peer and
currently nothing updates this information.
(2) We carry a lot of peer-related state around.

Both aspects could be simplified by externalising peer selection and
just requiring a specific peer ID where the request should be sent to.
We still have to maintain some peer related state due to the way
libp2p's swarm and network behaviour work (e.g. we must make sure to
always issue `NetworkBehaviourAction::SendEvent`s to peers we are
connected to, otherwise the actions die a silent death.

Another change implemented here is the use of protocol buffers as the
encoding for network messages. Certain individual fields of messages
are still SCALE encoded. There has been some discussion about this
in another PR (https://github.com/paritytech/substrate/pull/3452), so
far without resolution.

* Uncomment `Behaviour::light_client_request`.

* Add license headers.
