7850097fd0 Avoid propagating search . into containers /etc/resolv.conf 
* Adapt https://github.com/kubernetes/kubernetes/pull/109441 but
ensures that `search .` does not get propagated into containers'
/etc/resolv.conf. There is no reason to put `.` in a container's
search field and it causes issues for musl

f2d591fae6 change CPUCFSQuotaPeriod default value to 100us to match Linux default 
cpu.cfs_period_us is 100μs by default despite having an "ms" unit
for some unfortunate reason. Documentation:
https://www.kernel.org/doc/html/latest/scheduler/sched-bwc.html#management

The desired effect of that change is to match
k8s default `CPUCFSQuotaPeriod` value (100ms before that change)
with one used in k8s without the `CustomCPUCFSQuotaPeriod` flag enabled
and Linux CFS (100us, 1000x smaller than 100ms).

0064010cdd 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.
