Summary was not available with the correct information after the result being consumed. This fix, solve this issue by wrap the summary with the same treatment subscribe and then have on complete. This change also introduce a cache for capturing the last summary the stream complete, this way the summary function could be called after the results get consumed. PS: The same fixes were applied to keys()

The current driver implementation has only two options for record consumption, the default async/promise api and the reactive api.
In the async side, there is no simple way to interact over the results before consuming all the data stream and back-pressure the consumption. Meanwhile in the reactive, the back-pressure is implemented but this api usage depends on the knowledge of reactive programming and
RxJS. Another issue with our current reactive implementation is not having the way to configure the back-pressure or pause the stream consumption.The introduction of the Async Iterator is part of a group of improvements to make the driver more idiomatic and memory efficient.
