kubelet: eviction: avoid duplicate action on stale stats
Currently, the eviction code can be overly aggressive when synchronize() is called two (or more) times before a particular stat has been recollected by cadvisor. The eviction manager will take additional action based on information for which it has already taken actions.
This PR provides a method for the eviction manager to track the timestamp of the last obversation and not take action if the stat has not been updated since the last time synchronize() was run.

Set imagefs rank and reclaim functions when nodefs+imagefs share comm…
Fixes#31192
I decided that the behavior should match the current output of the kubelet summary API. With no dedicated imagefs, the ranking and reclaim functions will match the nodefs ranking and reclaim functions.
