[rt-tests,v1,00/13] JSON cleanups and more tests updated

The first two patches fixes the format string issue. Then there are a
couple of patches which fixes the common JSON entries (command line,
start_time, end_time).

Then there are patches which add the --output parameter to the missing
rt-tests programs.

All patches are also available at:
