We must add an ActionType named bypassWriteBlockingMode, and attach it to the restore role.

AuthorizationSession should maintain a cached copy of whether it is authorized for this ActionType on the cluster resource. This cache should be updated whenever a user's authorization right are added to, removed from, or updated within the Session.

We must add a mayBypassWriteBlockingMode method to the AuthorizationSession, which will access the cached value with as minimal overhead as possible.

We should include C++ unittests to validate that the cache update behaviour is reflected in mayBypassWriteBlockingMode.
