Update global cache timestamp more frequently

Browse Source 
There are some cases where a pod worker is woken up without a cache
update by the PLEG such as a pod termination. Then, the worker gets
stuck in `cache.GetNewerThan()` till the global cache timestamp is
updated by the PLEG. In order to unblock the stuck worker as early as
the Generic PLEG, this fix makes the Evented PLEG update the global
cache as frequently as the Generic PLEG.
