Summary:
This diff does the following:
- Updates the tracing crates to the latest versions available. Changes include:
- Experimental support for [Valuable](https://tokio.rs/blog/2021-05-valuable), which makes recording values much more like how serde does. Valuable also makes it easier to write a tracing-slog crate due to some implementation details of slog where buffering of values is necessary.
- Combinators for combining filters in tracing-subscriber.
- A `MakeWriter` implementation for `RollingFileAppender` in `tracing_appender`, which allows the `RollingFileAppender` without a background thread to being spun up.
- Reduced the disabled span drop overhead by 50-70%—this might be most apparent in tests that don't set a subscriber.
- Move the tokio-console off git dependencies and to published versions on crates.io.
This diff also updates the following, non-exhaustive list of crates:
- parking_lot
- prost
- thread_local
- tonic
- hyper
- httparse
- h2
allow-large-files
