opentelemetry: prepare to release v0.17.4

# 0.17.4 (July 1, 2022)

This release adds optional support for recording `std::error::Error`s
using OpenTelemetry's [semantic conventions for exceptions][exn-semconv].

### Added

- `Layer::with_exception_fields` to enable emitting `exception.message`
  and `exception.backtrace` semantic-convention fields when an `Error`
  is recorded as a span or event field ([#2135])
- `Layer::with_exception_field_propagation` to enable setting
  `exception.message` and `exception.backtrace` semantic-convention
  fields on the current span when an event with an `Error` field is
  recorded ([#2135])

Thanks to @lilymara-onesignal for contributing to this release!
