Added EnableNodeLogQuery field to kubelet/apis/config/types.go and
staging/src/k8s.io/kubelet/config/v1beta1/types.go, then executed.
`hack/update-codegen.sh`.
This new field will default to off and will need to be explicitly
enabled in addition to the NodeLogQuery gate to use the feature.
This change updates KMS v2 to not create a new DEK for every
encryption. Instead, we re-use the DEK while the key ID is stable.
Specifically:
We no longer use a random 12 byte nonce per encryption. Instead, we
use both a random 4 byte nonce and an 8 byte nonce set via an atomic
counter. Since each DEK is randomly generated and never re-used,
the combination of DEK and counter are always unique. Thus there
can never be a nonce collision. AES GCM strongly encourages the use
of a 12 byte nonce, hence the additional 4 byte random nonce. We
could leave those 4 bytes set to all zeros, but there is no harm in
setting them to random data (it may help in some edge cases such as
live VM migration).
If the plugin is not healthy, the last DEK will be used for
encryption for up to three minutes (there is no difference on the
behavior of reads which have always used the DEK cache). This will
reduce the impact of a short plugin outage while making it easy to
perform storage migration after a key ID change (i.e. simply wait
ten minutes after the key ID change before starting the migration).
The DEK rotation cycle is performed in sync with the KMS v2 status
poll thus we always have the correct information to determine if a
read is stale in regards to storage migration.

The name "PodScheduling" was unusual because in contrast to most other names,
it was impossible to put an article in front of it. Now PodSchedulingContext is
used instead.

Note that this fixes a bug in the existing `toBytes` implementation
which does not correctly set the capacity on the returned slice.
