[issue21650] add json.tool option to avoid alphabetic sort of fields

[Raymond Hettinger]

Raymond Hettinger added the comment:

To me, "--unsorted" implies arbitrary ordering such as the order generated by regular dictionaries.  I think the option should be "--order-preserving" or some such.  The option name needs to make it clear that the output is in the same order an the input.

As side from the option name, I'm +1 on the patch.  It is very annoying to look at scrambled JSON when the original presentation order made more logical sense.
