This PR fixes a possible panic caused by decoding a JSON document
followed by a YAML document that is shorter than the first json
document.
This can cause a panic because the stream already consumed the JSON
data. When we fallback to YAML reader, the YAML starts with a zero
offset while the stream consumed data is non-zero. This could lead into
consuming negative bytes because `d.yaml.InputOffset() -
d.stream.Consumed()` is negative which will cause a panic.

With StreamingCollectionEncodingToJSON and
StreamingCollectionEncodingToProtobuf, the WatchList must re-justify its
necessity. To prevent an ecosystem from building around a feature that
may not be promoted, we will stop serving list-via-watch until
performance numbers can justify its inclusion.
This also stops the kube-controller-manager from using the
list-via-watch by default. The fallback is a regular list, so during
the skew during an upgrade the "right" thing will happen and the new
StreamingCollectionEncoding will be used.
This change modifies the validation logic for ServiceCIDR updates
(`ValidateServiceCIDRUpdate`) to specifically permit upgrading a
single-stack ServiceCIDR (either IPv4 or IPv6) to a dual-stack
configuration.
This reconfiguration path is considered safe because it only involves adding
a new CIDR range without altering the existing primary CIDR. This
ensures that existing Service IP allocations are not disrupted.
Other modifications, such as:
- Downgrading from dual-stack to single-stack
- Reordering CIDRs in a dual-stack configuration
- Changing the primary CIDR during a single-to-dual-stack
reconfiguration
remain disallowed by the validation. These operations carry a higher
risk of breaking existing Services or cluster networking
configurations. Preventing these updates automatically encourages
administrators to perform such changes manually after carefully
assessing the potential impact on their specific cluster environment.
The validation errors and controller logs provide guidance when such
disallowed changes are attempted.
