What does this PR try to resolve?

The migrates CARGO_LOG logging from log to tracing.

tracing is already widely used among the ecosystem and rustc adopted it for a while. We've chatted about this a while back in the weekly meeting.

Last week in the office hour, epage, Muscraft, and arlosi have no objection to this when I mentioned this upcoming PR. ehuss seems to looking forward to the migration #12445 (comment). Hence posted this pull request.

How should we test and review this PR?

By commits. And please check if CARGO_LOG works for you.

Largely, a search & replace worked just fine. Only in util/network/http.rs I did a manual fix.

The format is also a bit different. Should we make it compatible? (I don't want to though)

# before
[2023-08-07T10:53:48Z DEBUG cargo::sources::registry::http_remote] loading config
# after
2023-08-07T10:43:47.867106Z DEBUG cargo::sources::registry::http_remote: loading config

By default log enables all levels, whereas the built-in fmt subscriber in tracing-subscriber enables up to INFO only. Is that a thing we need to consider? I do feel like INFO is a better default.

Additional information

-2 dependencies
+11 dependencies

Last year during 1.63.0 release cargo only had ~180 deps, but today it doubles the number to ~337 🥲.

Compatibility only matters if we intend people to parse it which I don't think we do.

The only other issue is usability which it is probably good enough

I'd like to call out the other change. By default log enables all levels, whereas the built-in fmt subscriber in tracing-subscriber enables up to INFO only. Is that a thing we need to consider? I do feel like INFO is a better default.
