Patching in the Distance-2 Graph Coloring to get in the new code + deprecations for the upcoming Trilinos release.
Adding @csiefer2 to reviewers because I touched the MueLu use of the call to d2_graph_color. I didn't change which algorithm is being used (still using the serial D2 coloring), but the function name was changed. The old one exists and prints out a deprecation warning, but since I'm here I might as well just point MueLu at the new call.
