* client/network-gossip/src/state_machine: Add unit test for on_incoming

Add two unit tests to ensure `on_incoming` is ingoring discarded
messages and reports and ignores messages from unknown peers.

* client/network-gossip/state_machine: Reduce indentation level

* client/network-gossip/bridge: Remove unnecessary into_iter

* client/network-gossip/state_machine: Report success after register check

* client/network-gossip/state_machine: Error not report on unregistered

`peers` contains all the peers we're connected to. If we receive a
message from a peer not in this list, that means there's an internal
problem within the local client. It's not the fault of the peer in
question.

With the above in mind instead of reducing the reputation of such peer,
log an error.

* 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.
