Docs: Feedback for Durable Executor Service

[Jarikkomarik]

Hi, I have some feedback about this page

Found DurableExecutorService error prone in cases when application is submitting larger amount of Tasks.

Example:
Having singe member application with 10 partitions and DurableExecutorService capacity parameter is 3.

I expect DurableExecutorService to be able to store 30 Tasks (Capacity * Partitions).

But due to random partition selection nature of DurableExecutorServcieProxy.getTaskPartitionId() where some partitions being full while others are not, I end up having "RejectExecutionException: Capacity (n) is reached!" exception, causing the specific task to be discarded, even if the application has not reached its maximum storage capacity.

I propose to add some logic that will count with filled partitions when it is generating partition id for Tasks.

I Know about about PartitionAware option, but this in not letting me fill partitions evenly.
