      Description

      See Enis Soztutar's comment in HBASE-16838

      https://issues.apache.org/jira/browse/HBASE-16838?focusedCommentId=15637803&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15637803

      But there is another scenario that we need small scan is that, we do not know the stop row but we only want a small set of results. For example, in the implementation of region locator, we will use small scan and set caching to 1 as we only need one row.

      So I think we need to add a new option(maybe called limit?) for the scan object, and deprecate the small option. And the server side modification should also be committed to branch-1 to simplify the logic of async client in 2.0.
