Take another shot at untangling the spaghetti orterun: fix for command line parsing orte-submit calls opal_init_util () before parsing out MCA command line options (-mca, -am, etc). This prevents mpirun from setting opal MCA variables for some frameworks as well as the MCA base. This is because when a framework is opened all of its variables are set to read-only. Eventually we want to lift this restriction on some MCA variables but since -mca is affected we must parse out the MCA command line options before opal_init_util(). This commit fixes the bug by adding a new option to opal_cmd_line_parse (ignore unknown option) so orte-submit can pre-parse the command line for MCA options.

long time before the OS schedules the orted to run again

routed OOB messages (for example) may be significantly delayed
