Redesign CR 2.0 Filtering functionality

Implement a new filtering framwork in CR 2.0 that is more intuitive for users:

• Show more clear information about which filters have been enabled and the selections that have been made.

• Fix customer filter saving, so that users can actually save custom filters.

• Create a more consistent approach for filter UX (i.e. drop downs).

• Rebuild the filter panel to be more flexible, so that we can more easily support needs for future whitelabeling.
