Improve logging for "switched to client" message

[h7x4]

This is mostly a usability issue, not a technical one.

Currently, I have to override RUST_LOG in order to see that the daemon detected my switch-keys and changed client. Compared to the other log messages, I believe this log message is equally important, and should be changed to a tracing::info.

Another change that would be nice, maybe the logs could use something more identifying than the client index? The hostname of the client would be optimal, but probably requires protocol changes. An alternative would be the clients IP address. It seems relatively trivial to store the address along with its mpsc sender. Not sure if this introduces any security risks though.

The relevant line:

rkvm/rkvm-server/src/server.rs

Line 210 in 825ed09

tracing::debug!("Switched to client {}", current);

Current log output:

[INFO  rkvm_server::server] 192.168.50.230:42178: Connected
[DEBUG rustls::server::hs] decided upon suite TLS13_AES_256_GCM_SHA384
[INFO  rkvm_server::server] 192.168.50.230:42178: TLS connected
[INFO  rkvm_server::server] 192.168.50.230:42178: Authenticated successfully
[DEBUG rkvm_server::server] Switched to client 1
[DEBUG rkvm_server::server] Switched to client 0

I don't mind creating a PR if I'm given green lights!

Great suggestion, fixed in 0.5.0, thanks.

[h7x4]

Thanks! But I wasn't able to find any changes in 0.5.0, nor master. Maybe you forgot to push it?

[htrefil]

Oh yes, you're right, sorry.
I'll release 0.5.1 later today with this fixed.

0.5.1 released, fixed.
