remove redundancy code in setCPUCgroupConfig
fix#53925
Signed-off-by: yanxuean <yan.xuean@zte.com.cn>
**What this PR does / why we need it**:
The check of burstableCPUShares is redundancy. We have done it in MilliCPUToShares. It is responsibility of MilliCPUToShares.
```
func (m *qosContainerManagerImpl) setCPUCgroupConfig(configs map[v1.PodQOSClass]*CgroupConfig) error {
........
// set burstable shares based on current observe state
burstableCPUShares := MilliCPUToShares(burstablePodCPURequest)
if burstableCPUShares < uint64(MinShares) {
burstableCPUShares = uint64(MinShares)
}

Cpu Manager - make CoreID's platform unique
**What this PR does / why we need it**:
Cpu Manager uses topology from cAdvisor(`/proc/cpuinfo`) where coreID's are socket unique - not platform unique - this causes problems on multi-socket platforms.
All code assumes unique coreID's (on platform) - `Discovery` function has been changed to assign CoreID as the lowest cpuID from all cpus belonging to the same core. This can be expressed as:
`CoreID=min(cpuID's on the same core)`
Since cpuID's are platform unique - above gives us guarantee that CoreID's will also be platform unique.

Eliminate extra CRI call during processing cpu set
**What this PR does / why we need it**:
Encountered this during `kubernetes/frakti` node e2e test.
When cpuset is not set, there's still plenty of `runtime.UpdateContainerResources` been called, which seems unnecessary.
cc @ConnorDoyle Make sense? Fixes: #53304

**Release note**:

Only do UpdateContainerResources when cpuset is set

Update Cadvisor Dependency
Fixes: https://github.com/kubernetes/kubernetes/issues/51832
This is the worst dependency update ever...
The root of the problem is the [name change of Sirupsen -> sirupsen](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276). This means that in order to update cadvisor, which venders the lowercase, we need to update all dependencies to use the lower-cased version. With that being said, this PR updates the following packages:
`github.com/docker/docker`
- `github.com/docker/distribution`
- `github.com/opencontainers/go-digest`
- `github.com/opencontainers/image-spec`
- `github.com/opencontainers/runtime-spec`
- `github.com/opencontainers/selinux`
- `github.com/opencontainers/runc`
- `github.com/mrunalp/fileutils`
- `golang.org/x/crypto`
- `golang.org/x/sys`
- `github.com/docker/go-connections`
- `github.com/docker/go-units`
- `github.com/docker/libnetwork`

Make /var/lib/kubelet as shared during startup
This is part of ~~https://github.com/kubernetes/community/pull/589~~https://github.com/kubernetes/community/pull/659
We'd like kubelet to be able to consume mounts from containers in the future, therefore kubelet should make sure that `/var/lib/kubelet` has shared mount propagation to be able to see these mounts.
On most distros, root directory is already mounted with shared mount propagation and this code will not do anything. On older distros such as Debian Wheezy, this code detects that `/var/lib/kubelet` is a directory on `/` which has private mount propagation and kubelet bind-mounts `/var/lib/kubelet` as rshared.
Both "regular" linux mounter and `NsenterMounter` are updated here.

Release note:
```release-note
Kubelet re-binds /var/lib/kubelet directory with rshared mount propagation during startup if it is not shared yet.
```
