NIFI-2346: 

- Introducing data resource for authorizing provenance events and queue listing.
- Authorizing entire proxy chain for data resource and data transfer resource.
NIFI-2338:
- Ensuring that replay authorization only happens once.

- Allowing users with access to policies for a component to be able to access all policies for that component.
-- Includes the component, data, data transfers, and policies.
- Fixing drop request completion to update the correct queued field.
- Fixing access control check for listing and emptying queues.
- Reseting selected policy when re-opening the policy management page.
- Fixing button/link visibility for available actions in policy management page.
- Fixing policy issues with policy removal when the underlying component is deleted.
- Updating file authorizer seeding to grant data access to node's in the cluster.

This closes #720.
