-  Remove already deprecated options `resyncperiod` and `upstream` in the Kubernetes plugin.
  -  Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
  -  The federation plugin (allows for v1 Kubernetes federation) has been removed.

### Breaking Changes


`tf.keras`:

* Allow having empty paths in *path operations* used with `include_router` and a `prefix`.
    * This allows having a router for `/cats` and all its *path operations*, while having one of them for `/cats`.
    * Now it doesn't have to be only `/cats/` (with a trailing slash).
