deps: Update tracing-subscriber to 0.2.16 (#927)

This picks up tokio-rs/tracing#1247, tokio-rs/tracing#1248,
tokio-rs/tracing#1251, and tokio-rs/tracing#1254. Collectively, these
changes should result in a significant performance improvement when
using `tracing-log`'s compatibility layer for converting legacy `log`
records to `tracing` events.

Since we have some dependencies which use the `log` crate, this should
hopefully reduce the overhead of those dependencies' logging. I'm not
sure how much `log` we have in the hot path by this point, but it's
probably a good idea to pick up the change regardless.
