Authorization policies

Following are the core policies that the authorization module follows. Detailed policies for entities are listed in the table after that. For new entities and entities not listed here, these core policies should be followed.

Create needs a WRITE on the parent
Delete needs an ADMIN on the entity
Delete all deletes all entities the user has privileges for and shows errors for the ones not deleted.
List needs a READ/WRITE/ADMIN on the entity.
Get needs a READ on the entity and READ on the parent.
Setting preferences needs WRITE on the entity
Getting preferences needs READ on the entity
Update needs ADMIN on the entity
Adding metadata needs ADMIN on the entity
Reading metadata needs READ on the entity
