The current implementation in Kademlia relies on an external address to determine if it should be in client or server mode. However there are instances where a node, which may know an external address, wishes to remain in client mode and switch to server mode at a later point.
This PR introduces `Kademlia::set_mode`, which accepts an `Option<Mode>` that would allow one to set `Mode::Client` for client mode, `Mode::Server` for server mode, or `None` to determine if we should operate as a client or server based on our external addresses.

This resolves an issue where our tests were depending on the number of network interfaces available on the local machine.

Instead of exposing the time to establish a connection, the time to upload the bytes and the time to download the bytes, expose a single time including all three.
The rational here is, that differentiation of the three is flawed. E.g. when does one stop the upload timer and start the download timer? When the last byte is sent? When the last byte is flushed? When the first byte is received?

Using workspace inheritance breaks `cargo release` because it cannot resolve that the dev-dependencies should only use a `path` and not a version.

Currently, the kademlia behaviour can only learn that the remote node supports kademlia on a particular connection if we successfully negotiate a stream to them.
Using the newly introduced abstractions from #3651, we don't have to attempt to establish a stream to the remote to learn whether they support kademlia on a connection but we can directly learn it from the `ConnectionEvent::RemoteProtocolsChange` event. This happens directly once a connection is established which should overall benefit the DHT.
Clients do not advertise the kademlia protocol and thus we will immediately learn that a given connection is not suitable for kadmelia requests. We may receive inbound messages from it but this does not affect the routing table.

Rewrite `libp2p-perf` protocol using `libp2p-request-response`. Additionally adjust to latest conventions, e.g. the final JSON output.

This modification removes deprecated dependency `wasm_timer` and enables wasm compatibility on the gossibsup protocol by simply substituting the `wasm_timer::Instant` with `instant::Instant`(which supports `fn checked_add`) and `wasm_timer::Interval` with `futures_ticker::Ticker`.

Peer discovery with mDNS can be very slow, particularly if the first mDNS query is lost. This patch resolves it by adjusting the timer with an adaptive initial interval. We start with a very short timer (500 ms). If a peer is discovered before the end of the timer, then the timer is reset to the normal query interval value (300s), otherwise the timer's value is multiplied by 2 until it reaches the normal query interval value.
