Allow rangeSlice queries to be start/end inclusive/exclusive 
-------------------------------------------------------------

                 Key: CASSANDRA-3749
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3749
             Project: Cassandra
          Issue Type: Sub-task
          Components: Core
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
             Fix For: 1.1
         Attachments: 3749.patch

Currently, given two keys k1 and k2, we can only do a rangeSlice on the 
intervals (k1, k2] (Range) and [k1, k2] (Bounds). CQL goes around this 
"manually", by querying one more row if the start is exclusive and removing the 
start/end post-query if necessary. This doesn't work however with the new 
option introduced by CASSANDRA-3742. So this ticket proposes to add support 
(internally) for doing a rangeSlice for the intervals (k1, k2) an [k1, k2).
