 *  New: Add tags to `Call`, including computable tags. Use this to attach application-specific
    metadata to a `Call` in an `EventListener` or `Interceptor`. The tag can be read in any other
    `EventListener` or `Interceptor`.

    ```kotlin
      override fun intercept(chain: Interceptor.Chain): Response {
        chain.call().tag(MyAnalyticsTag::class) {
          MyAnalyticsTag(...)
        }
