Promote Local storage capacity isolation feature to GA

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.

This feature allows users to set request/limit for container's ephemeral storage and manage it in a similar way as cpu and memory. It also allows setting sizeLimit for emptyDir volume, which will trigger pod eviction if disk usage from the volume exceeds the limit. This feature depends on the capability of detecting correct root file system disk usage. For certain systems, such as kind rootless, if this capability cannot be supported, the feature LocalStorageCapacityIsolation should be disabled. Once disabled, user should not set request/limit for container's ephemeral storage, or sizeLimit for emptyDir. Default: true",
