Add ScanHBase (new) processor to retrieve records from HBase tables.
Today there are GetHBase and FetchHBaseRow. GetHBase can pull entire table or only new rows after processor started; it also must be scheduled and doesn't support incoming . FetchHBaseRow can pull rows with known rowkeys only.
This processor could provide functionality similar to what could be reached by using hbase shell, defining following properties:
-scan based on range of row key IDs
-scan based on range of time stamps
-limit number of records pulled
