Looks good, but would be useful to have a few unit and / or integration
tests. Also, `AccessControl.hasAccess(...)` methods are currently being called
in BaseBrokerREquestHandler:
```
Line 189:
// First-stage access control to prevent unauthenticated requests from
using up resources. Secondary table-level
// check comes later.
boolean hasAccess =
_accessControlFactory.create().hasAccess(requesterIdentity);
Line 295:
// Second-stage table-level access control
boolean hasTableAccess =
_accessControlFactory.create().hasAccess(requesterIdentity,
serverBrokerRequest);
```
I am wondering if something similar can be done for all DML/DDL statements
as well to avoid either accidental or malicious usecases where a user who
normally runs SELECT statements ends up running an INSERT statement with valid
S3 credential to insert bad data into a Pinot table (?).
