`--enforce-node-allocatable` with a default value of `pods` is added which will make kubelet create a top level cgroup for all pods to enforce Node Allocatable. Optionally, `system-reserved` & `kube-reserved` values can also be specified separated by comma to enforce node allocatable on cgroups specified via `--system-reserved-cgroup` & `--kube-reserved-cgroup` respectively. Note the default value of the latter flags are "". ([#41234](https://github.com/kubernetes/kubernetes/pull/41234), [@vishh](https://github.com/vishh))...

Added support for specifying `controlplane` or `cluster` egress selectors in JWT authenticators via the `issuer.egressSelectorType` field in the `AuthenticationConfiguration.jwt` array. If unset, the previous behavior of using no egress selector is preserved. This functionality requires the `StructuredAuthenticationConfigurationEgressSelector` beta feature gate (enabled by default).

- CRD validation now strictly enforces ranges for numeric formats (int32, int64, float, double) when specified in the schema.
