1. Define ContainerResizePolicy and add it to Container struct.
2. Add ResourcesAllocated and Resources fields to ContainerStatus struct.
3. Define ResourcesResizeStatus and add it to PodStatus struct.
4. Add InPlacePodVerticalScaling feature gate and drop disabled fields.
5. ResizePolicy validation & defaulting and Resources mutability for CPU/Memory.
6. Various fixes from code review feedback (originally committed on Apr 12, 2022)
KEP: /enhancements/keps/sig-node/1287-in-place-update-pod-resources
PVC and containers share the same ResourceRequirements struct. The Claims field
in it only makes sense when used in containers. When used in a PVC, the field
should have been rejected by validation. This was overlooked when introducing
it, so now persisted objects might have it set and/or people may have started
to rely on it being accepted even when it has no effect.
Therefore we cannot reject it in validation anymore, but we can still strip
it out on create or update.
The Services API should warn users about some IP addresses
representations, mainly because some of them are not allowed
by the golang std parsers since go 1.17
Specifically:
- IPv4 addresses with leading zeros, that may cause security risks
- IPv6 addresses in non canonical format, that may cause problems
with controllers hotlooping or cause security issues

resource.PodScheduling.
- New API field .spec.schedulingGates
- Validation and drop disabled fields
- Disallow binding a Pod carrying non-nil schedulingGates
- Disallow creating a Pod with non-nil nodeName and non-nil schedulingGates
- Adds a {type:PodScheduled, reason:WaitingForGates} condition if necessary
- New literal SchedulingGated in the STATUS column of `k get pod`
* Code Refactoring

This commit just adds a validation according to KEP-127. We check that
only the supported volumes for phase 1 of the KEP are accepted.

This change is to promote local storage capacity isolation feature to GA
At the same time, to allow rootless system disable this feature due to
unable to get root fs, this change introduced a new kubelet config
"localStorageCapacityIsolation". By default it is set to true. For
rootless systems, they can set this configuration to false to disable
the feature. Once it is set, user cannot set ephemeral-storage
request/limit because capacity and allocatable will not be set.
