**Warning**: The logs generated by this interceptor when using the `HEADERS` or `BODY` levels have
the potential to leak sensitive information such as "Authorization" or "Cookie" headers and the
contents of request and response bodies. This data should only be logged in a controlled way or in
a non-production environment.

You can redact headers that may contain sensitive information by calling `redactHeader()`.
```java
logging.redactHeader("Authorization");

    server.enqueue(
      MockResponse
        .Builder()
        .addHeader("SeNsItIvE", "Value")
        .addHeader("Not-Sensitive", "Value")
        .build(),
    )
    val response =
      client
        .newCall(
          request()
            .addHeader("SeNsItIvE", "Value")
            .addHeader("Not-Sensitive", "Value")
            .build(),
        ).execute()
    response.body.close()

 *  Breaking: Move `gzip` from `RequestBody` to `Request.Builder`. This new API handles both
    compressing the request body and also adding the corresponding `Content-Encoding` header. Note
    that this function is sensitive to when it is called: the response body must be supplied before
    it can be compressed.

 *  Breaking: Remove `AddressPolicy`, `AsyncDns`, and `ConnectionListener` from the public API. We
