This allows the state of restartable init containers to be transitioned
from terminated to non-terminated even for pods with RestartPolicyNever
or RestartPolicyOnFailure.
Inline the LoadBalancerSourceRanges parsing to make it more obvious
what it's requiring (and more importantly, *not* requiring), and
change it to use IsValidCIDR as well.
Move apivalidation.ValidateCIDR to apimachinery, and rename it and
change its return value to match the other functions.
Also, add unit tests.
(Also, while updating NetworkPolicy validation for the API change, fix
a variable name that implied that IPBlock.Except[] is IP-valued rather
than CIDR-valued.)
This commit defines the ClusterTrustBundlePEM projected volume types.
These types have been renamed from the KEP (PEMTrustAnchors) in order to
leave open the possibility of a similar projection drawing from a
yet-to-exist namespaced-scoped TrustBundle object, which came up during
KEP discussion.
* Add the projection field to internal and v1 APIs.
* Add validation to ensure that usages of the project must specify a
name and path.
* Add TODO covering admission control to forbid mirror pods from using
the projection.
Part of KEP-3257.
When defining a ClusterIP Service, we can specify externalIP, and the
traffic policy of externalIP is subject to externalTrafficPolicy.
However, the policy can't be set when type is not NodePort or
LoadBalancer, and will default to Cluster when kube-proxy processes the
Service.
This commit updates the defaulting and validation of Service to allow
specifying ExternalTrafficPolicy for ClusterIP Services with
ExternalIPs.

The fact that the .status.loadBalancer field can be set while .spec.type
is not "LoadBalancer" is a flub. Any spec update will already clear
.status.ingress, so it's hard to really rely on this. After this
change, updates which try to set this combination will fail validation.
Existing cases of this will not be broken. Any spec/metadata update
will clear it (no error) and this is the only stanza of status.
New gate "AllowServiceLBStatusOnNonLB" is off by default, but can be
enabled if this change actually breaks someone, which seems exceeedingly
unlikely.
