Add row and col scaling functions to distributed matrix

[fritzgoebel]

This PR adds a row_scale and a col_scale function to the distributed matrix. This functionality is needed in openCARP.

• The row scaling is straight forward, with a distributed vector of scaling coefficients that has the same row partitioning as the matrix, we can just scale the rows of local and non-local matrices with the local vectors.
• For column scaling, we need to communicate the non-local scaling coefficients to scale the columns of the non-local matrices. This can be simply done with the matrix's communicate.
