A package with no imports is initialized by assigning initial values
to all its package-level variables followed by calling all <code>init</code>
functions in the order they appear in the source, possibly in multiple files,
as presented to the compiler.
If a package has imports, the imported packages are initialized

   * If you're upgrading to OkHttp 4.6 and would like to retain the previous behavior, install this
   * as a **network interceptor**. It will strip the `Location` header of impacted responses to
   * prevent the redirect.

   * OkHttpClient client = client.newBuilder()

* The implicit registration of Prometheus metrics for request count and latency have been removed, and a plug-able interface was added. If you were using our client libraries in your own binaries and want these metrics, add the following to your imports in the main package: "k8s.io/pkg/client/metrics/prometheus".
