Added a recurse option to automatically recurse into sub workflows.
PM-730 added support for auto indenting the sub workflow console messages.
PM-730  The sub workflows failures are better demarcated and we log
the submit directory for the workflows in the summary now.
PM-730 setting the quiet mode was disabling the recursion. fixed.
PM-730 put in recursion support for the --files option, where we do
not query the stampede database but go through files in the submit
directory. this option is deprecated in the long term
