    SLING-9593: Abstract out binary handling to allow plugging of different stores (#4)
    
    * SLING-9593: Abstract out binary handling to allow plugging of different stores
    
    - Introduced an interface BinaryStore and JcrBinaryStore as the default implementation storing the binaries in JCR with no change in the existing strategy of storing based on size.
    
    * SLING-9593: Abstract out binary handling to allow plugging of different stores
    
    - Simplifying the interface as dependent implementations can also be simplified
