[client] Support cumulative acknowledgement at partitioned topic

[fxbing]

Is your feature request related to a problem? Please describe.
Currently cumulative acknowledgement is not supported on partitioned topics.

Describe the solution you'd like
Do acknowledgeCumulative() on all partitions for partitioned topics.

Describe alternatives you've considered
No other alternative. Users need to implement it themselves

Additional context
It would be much easier for people to use if we support acknowledgeCumulative() at partitioned topics.

It seems we can acknowledgeCumulative on partitioned topics but the result is to ack the specific partition.

Moved to the Discussion forum since here's no design and stale for a long time. We don't use issue track to track wishing list.
