Description

When implementing higher level stores on top of HBase it is necessary to allow dynamic control over how long KVs must be kept around.
Semi-static config options for ColumnFamilies (# of version or TTL) is not sufficient.

This can be done with a few additional coprocessor hooks, or by makeing Store.ScanInfo pluggable.

Was:
The simplest way to achieve this is to have a pluggable class to determine the smallestReadpoint for Region. That way outside code can control what KVs to retain.
