This patch removes any unused parameters in the v2 and v3 api's.
In order to find which parameters were unused, I wrote a script
that found all the parameters used in the `parameters.yaml` files,
then is searched the same api directory (ex: v3/, v3-ext/, etc.)
for any reference to these parameters. Anything unreferenced was
flagged and then removed.
