    [FLINK-3919][flink-ml] Distributed Linear Algebra: row-based matrix

    First PR of the Distributed Linear Algebra contribution.
    
    It contains a minimal implementation of a row-based distributed matrix and the following operations:
    
    Build from COO
    
    Conversion from distributed to: 
    * local dense format
    * local sparse format 
    * local COO format.
    
    by-row UDF on two matrices
    sum
    subtraction
