Consolidated ViewSets for ThrillWiki API v1.

This module contains ViewSets that are shared across domains or don't fit
into specific domain modules. Domain-specific ViewSets have been moved to:
- Parks: api/v1/parks/views.py
- Rides: api/v1/rides/views.py
- Accounts: api/v1/accounts/views.py
- History: api/v1/history/views.py
- Auth/Health/Trending: api/v1/views/
