- New APIs to allow adding/removing pods from pre-calculated prefilter state in the scheduling framework ([#82912](https://github.com/kubernetes/kubernetes/pull/82912), [@ahg-g](https://github.com/ahg-g))
- Added Clone method to the scheduling framework's PluginContext and ContextData. ([#82951](https://github.com/kubernetes/kubernetes/pull/82951), [@ahg-g](https://github.com/ahg-g))

pkg net/http, func NewRequestWithContext(context.Context, string, string, io.Reader) (*Request, error)
pkg net/http, method (Header) Clone() Header
pkg net/http, method (*Request) Clone(context.Context) *Request
pkg net/http, method (*Transport) Clone() *Transport
pkg net/http, type Server struct, BaseContext func(net.Listener) context.Context

These changes are reflected in the following Kubernetes enhancements:
([#625](https://github.com/kubernetes/enhancements/issues/625))

#### Additional Notable Feature Updates

### Bug or Regression

- ## Changelog
  
  ### General
  - Fix priority expander falling back to a random choice even though there is a higher priority option to choose
  - Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions
  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)

        * When a `response_model` is declared, the same `response_model` type declaration won't be used as is, it will be "cloned" to create an new one (a cloned Pydantic `Field` with all the submodels cloned as well).
