Update to Envoy ff49762696b2e6ed3f408a22e1f7a1b7d2487318 (Oct 11th)

- Note: needed to define ABSL_LEGACY_THREAD_ANNOTATIONS.
Looks like some of absl's annotations have been renamed
- fmt started complaining about StringPiece as an input.
Needed to tweak logging and introduce some tech debt to
strip newlines at the end of the log line without adding
memory copying
