* fix: shut off all uneeded endpoints
We recently added a new feature to FAB allowing to whitelist the needed
endpoints in ModelView and ModelRestApi.
First, we set our base wrapper class to an empty set, forcing each
class inheriting from it to explicitely turn on the endpoints that
Superset intends to use.
Second, we go ModelView by ModelView to whitelist the actual endpoints
used in the app.
Notes:
* as a result a large set of [unneeded] permissions should be cleaned up
* outside of the "private" use of endpoints in the app, people that have
been using endpoints in their environment for other purposes may
experience loss of functionality
* Tweaking
* Reduce the amount of endpoints using white lists
* Fix, included needed endpoints for dashboard and druid
* Drying things up
* fixes
* limiting more endpoints
* Read only on some FAB model views
* fixing some tests
* fixes
* Fixing more tests
* Addressing comments
* Drying up route_methods
* further drying
