Filter CCC params for C/S

[jdebacker]

This PR adds a filter so that not all the CCC parameters are available on the C/S web app. The reason is two-fold:

1. Some of the individual income tax rate parameters are redundant on the app since Tax-Calculator is run in each C/S run.
2. Some parameters, such as those around household savings behavior, are too "in the weeds" and unlikely to be changed by C/S users. Removing them will reduce clutter and confusion on the C/S input page.
