set leveled logging (v=4) for 'updating container' message
**What this PR does / why we need it**:
Currently cpu_manager.go logs a line for every pod at every reconcilePeriod (10 sec default) when it reconciles and updates the pod's cpuset setting. This creates a lot of logging information that is not very interesting and we should suppress that by default by increasing the logging level.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#54804
**Special notes for your reviewer**:
I chose V(4) because that seems to be a popular level for messages at this detail. Happy to follow logging guideline if there is any.
**Release note**:
``` kubelet: cpu_manager logs informative reconcile message at V(4) to reduce clutter ```
