I made fast experiment and the output for the code proposed here and existed
in the RDMAtool - result the same. So the good thing will be to delete the
function from the RDMA after print_on_off_bool() will be improved.

However I don't understand why print_on_off_bool() is implemented in
utils.c and not in lib/json_print.c that properly handles JSON context,
provide colorized output and doesn't require to supply FILE *fp.

Thanks
