Use `tracing` as our logger rather than `slog`

[Rachelint]

Describe This Problem

slog is an outdated crate maintained by nobody now. And the most popular one is tokio's tracing. In fact, we have used tracing in our project but not include its logger, how about let's make use of it.

Proposal

Maybe can make it referring to influxdb_iox

I'll vote for it if there is no performance issue.
