Updating model to only include the non-deprecated fields.  This work is a follow on to ECOM-7195 and SHOULD NOT be merged until that PR is merged.

ECOM-7195

The (now deprecated) programs service had several fields to set up configuration of the API.  We are removing the property/field references in codeas the first part of deprecating the model fields.  Also being removed are the model properties.

This commit contains back end changes necessary to load programs from the catalog in all contexts. The existing program munging utility is applied as late as possible to avoid conflating this work with changes to the front end; those will be made separately.
