content host installed_products array needs to pass product arch and version to candlepin when specified
The host_subscriptions API takes an installed_products array and converts it to camelCase (product_id to productId). The incoming products may also indicate their arch and version (eg. x86_64 and 6.4). These attributes need to be passed on as well.
fixes #14593 - include arch and version when processing incoming params
