Combine settings suggestion and condition.

- Add a flag in dashboard feature provider to specify whether to use the
combined UI for suggestions and conditions.
- Move Conditions below Suggestions.
- Add dashboard entity for condition and suggestion container, and
  wrap the condition and suggestion list inside the container. The
  container itself will be a single dashboard item, and within it will
  be the list of suggestion or condition.
- Add suggestion/condition header that will show the combined info for
  the conditions and suggestion data, and have the expand button to
  control expanding both the suggestion and condition list.
- Change the individual condition card to be always expanded, and
remove the logic to collapse/expand individual condition card.
- Remove the divider between the action button and condition detail
  within each condition card.
- Add suggestion/condition footer for collapsing the whole suggestion and
  condition list.
