Bastian Köcher d551fe6613 sc-cli: Fix bugs after switching to clap3 (#10920)
* sc-cli: Fix bugs after switching to clap3

Before switching to clap3 we support cli options like `--reserved-nodes A B` and after you needed to
pass `--reserved-nodes` cli option multiple times `--reserved-nodes A --reserved-nodes B`. This is
fixed by setting `multiple_occurrences(true)` option. This also done for all the other `Vec` cli
options in `sc-cli`. Besides that `--sync` wasn't supporting case insensitive parsing of the value.
This is now also supported. For both regressions a test is added. Besides that the pr removes all
the `rename_all = PascalCase` attributes, because they are not needed. All other `ArgEnum`s were
checked and all are already using `ignore_case(true)`.

* Bring back `PascalCase`, because otherwise it falls back to `kebab-case`...

Adrian Catangiu c1865988df Name changes for GrandPa and Beefy notifications protocols (#10463)
* grandpa: update notif protocol name

* grandpa: add chain id prefix to protocol name

* grandpa: beautify protocol name handling

* grandpa: prepend genesis hash to protocol name

* chain-spec: add optional 'fork_id'

'fork_id' is used to uniquely identify forks of the same chain/network
'ChainSpec' trait provides default 'None' implementation, meaning this
chain hasn't been forked.

* grandpa: protocol_name mod instead of struct

* beefy: add genesis hash prefix to protocol name

* chainspec: add fork_id

* grandpa: simplify protocol name

* grandpa: contain protocol name building logic

* beefy: contain protocol name building logic

* grandpa: fix tests

* fix merge damage

* fix docs reference visibility

* .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: 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 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.

Toralf Wittner 421ef498f4 network: Only insert global addresses into the DHT. (#5735)
* network: Only insert global addresses into the DHT.

Currently every address reported via libp2p-identify is inserted into
the DHT which thus contains a multitude of unreachable addresses such
as from 127.0.0.0/8 or 10.0.0.0/8.

Issue #5099 suggested a dedicated service over UDP to gauge the
reachability of an address, which would however incur extra I/O costs
and be of limited use.

As an alternative and simpler tactic, this PR only allows global IP
addresses to be inserted into the DHT unless an explicit command-line
flag `--allow-non-global-addresses-in-dht` is given or a node is
started with `--dev`. This opt-in behaviour is meant to allow
site-local networks to still make use of a DHT.

* Enable non-global in more test setups.

* Replace command-line option with different name.

* Another test fix.
