/**
 * This class acts as the REST Resource endpoint against which integration tests are executed.
 * This is used instead of the real F4 REST API for two reasons:
 * - These integration tests are intended to test the AuthZ functionality, not the F4 REST API
 * - A circular dependency between fcrepo-auth-common <--> fcrepo-http-api is bad
