Hunk report acceleration

We can easily accelerate our searches, which is critical for business. The idea behind Hunk is easy: the same search on the same data always gives the same result. In other words, same search + same data = same results. In the case of acceleration, Hunk caches the results and returns them on demand. Moreover, it gives us the opportunity to choose a data range for a particular data summary. In other words, if the data change is due to a fresh portion of events, then the accelerated report will rebuild the data summary in order to meet the requirements of the particular data range. Technically, we just cache the map phase in HDFS. When we run the accelerated search, Hunk just returns straight to us. There are four main steps in running an accelerated search:

1. The scheduled job builds a cache.

2. Find cache hits.

3. Stream the results to a search head.

4. Reduce on the search head.
