mca/base: standize MCA verbosity levels
Up until this point we have had inconsistent usage for MCA verbosity levels. This commit attempts to correct this by recommending components use these standard levels: none (-1), error (0), component (10), warn (20), info (40), trace (60), debug (80), and max (100). master commit open-mpi/ompi@8cbf743 Signed-off-by: Nathan Hjelm <[email protected]>
