Description

For Malhar feature APEXMALHAR-1938 needed a change in StorageAgent interface which was not released when that feature was contributed so we had added copy of StorageAgent interface in Malhar-Library.
https://github.com/apache/incubator-apex-malhar/blob/master/library/src/main/java/com/datatorrent/lib/util/StorageAgent.java

Since those changes are released as part of Apex Core 3.3.0 release we no longer require redundant StorageAgent interface present in Malhar-library.

Also need to update AbstractKeyValueStorageAgent to implement StorageAgent from Apex-core than one present in Malhar-library for concrete implementation of StorageAgents to work.
