UpdatePolicy class

Defines authorization policy for update operations.

The purpose of this class is to expose the method actionToDemandOnPrincipal that determines the required shares, containing which action, that each entity that is to be updated is required.

For example, if the method determines that the action is 'write', then all update operations will only update entities that have a share with the 'write' action for the principal. If the actionToDemandOnPrincipal returns an empty string, then the update actions are not limited by the shares each entity has for the user.

This policy also determines whether updates are limited to the same tenant as the principal's.
