We uopdated runCondorTool to use a tool timeout of 10
and more tries. We have it tell runcmd both that any result is fine and
give it a string to place in it's header. #3932
Allow emit_string to be in the hash of options for runcmd and when it is set
add it to the runcmd output header #3932
Moving the master verion of this test which has been hardened
by using runToolNTimes as a system call replacement and
runCondorTool as a back tick method. runToolNTimes uses
runCondorTool and both are in the updated CondorTest.pm.
runCondorTool now ensures runcmd not to die in case of an error #3932
Re-worded (and hopefully clarified) the definitions of
DAGMAN_DEFAULT_NODE_LOG and DAGMAN_ALWAYS_USE_NODE_LOG.
