* Creates a new EntryTaskScheduler that will run all second operations in bulk.
* Imagine a write-behind map where dirty entries will be stored in bulk.
* Note that each key can only occur once; meaning you cannot delay the execution.
* For example, once an entry is marked as dirty, it will run in write-delay-seconds,
* even if the entry is updated again within write-delay-seconds.
* Two things to remember:
* 1. A key cannot be re-scheduled (postponing its execution).
* 2. All entries scheduled for a given second will be executed once by your
* SecondBulkExecutor implementation.
* Once a key is executed, it can be re-scheduled for another execution.
* <p/>
* EntryTaskScheduler implementation is thread-safe.
