Tpetra: Add computeRowOneNorms function
Created by: mhoemmen

@vbrunini requests that we add Tpetra::computeRowOneNorms
. His app has the option to scale linear systems only on the left side, only by row norms. The existing Tpetra::computeRowAndColumnOneNorms
function already has an option not to compute column norms (set assumeSymmetric=true
), but it still communicates the row norms to the column Map distribution for symmetric scaling. @vbrunini doesn't even want to communicate the row norms, since he doesn't plan to right-scale with them.
