This commit is the main API piece of KEP-3257 (ClusterTrustBundles).
This commit:
* Adds the certificates.k8s.io/v1alpha1 API group
* Adds the ClusterTrustBundle type.
* Registers the new type in kube-apiserver.
* Implements the type-specfic validation specified for
ClusterTrustBundles:
- spec.pemTrustAnchors must always be non-empty.
- spec.signerName must be either empty or a valid signer name.
- Changing spec.signerName is disallowed.
* Implements the "attest" admission check to restrict actions on
ClusterTrustBundles that include a signer name.
Because it wasn't specified in the KEP, I chose to make attempts to
update the signer name be validation errors, rather than silently
ignored.
I have tested this out by launching these changes in kind and
manipulating ClusterTrustBundle objects in the resulting cluster using
kubectl.
This change updates the API server code to load the encryption
config once at start up instead of multiple times. Previously the
code would set up the storage transformers and the etcd healthz
checks in separate parse steps. This is problematic for KMS v2 key
ID based staleness checks which need to be able to assert that the
API server has a single view into the KMS plugin's current key ID.

The change to registrytest was found by liggitt to mitigate a NPE error.
This is necessary since ingress is a cohabitating resource that is not
stored in the default version for the networking resource.

Currently setting watch cache size for a given resource does not disable
the watch cache. This commit adds a new `default-watch-cache-size` flag
to map to the existing field, and refactors how watch cache sizes are
calculated to bring all of the code into one place. It also adds debug
logging to startup to allow us to verify watch cache enablement in
production.
