The slackdriver build is unrelated to this PR changes - @djc if you know what could be causing this:

error[E0308]: `?` operator has incompatible types
   --> opentelemetry-stackdriver/src/lib.rs:417:28
    |
417 |             authenticator: authenticator.build().await?,
    |                            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected `HttpsConnector<HttpConnector>`, found a different `HttpsConnector<HttpConnector>`
    |
    = note: `?` operator cannot convert from `Authenticator<yup_oauth2::hyper_rustls::HttpsConnector<HttpConnector>>` to `Authenticator<hyper_rustls::HttpsConnector<HttpConnector>>`
    = note: `HttpsConnector<HttpConnector>` and `HttpsConnector<HttpConnector>` have similar names, but are actually distinct types
note: `HttpsConnector<HttpConnector>` is defined in crate `hyper_rustls`
   --> /home/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/hyper-rustls-0.25.0/src/connector.rs:22:1
    |

    | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
note: `HttpsConnector<HttpConnector>` is defined in crate `hyper_rustls`

    |
19  | pub struct HttpsConnector<T> {
    | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    = note: perhaps two different versions of crate `hyper_rustls` are being used?

I think that's because yup-oauth2 made a semver-compatibility mistake... I notified the maintainer.
