[Authorization] Support GET_BACKLOG_SIZE topic op after enable auth

[yuruguo]

Motivation

Currently, we can get the backlog size of a topic through bin/pulsar-admin topics get-backlog-size tn1/ns1/tp1, however I found that PulsarAuthorizationProvider lacks support for topic operation GET_BACKLOG_SIZE when verifying the role's authorization, code as below:

pulsar/pulsar-broker/src/main/java/org/apache/pulsar/broker/admin/impl/PersistentTopicsBase.java

Line 2767 in b99f75e

validateTopicOperation(topicName, TopicOperation.GET_BACKLOG_SIZE);

pulsar/pulsar-broker-common/src/main/java/org/apache/pulsar/broker/authorization/PulsarAuthorizationProvider.java

Lines 569 to 599 in b99f75e

	switch (operation) {
	case LOOKUP:
	case GET_STATS:
	case GET_METADATA:
	isAuthorizedFuture = canLookupAsync(topicName, role, authData);
	break;
	case PRODUCE:
	isAuthorizedFuture = canProduceAsync(topicName, role, authData);
	break;
	case GET_SUBSCRIPTIONS:
	case CONSUME:
	case SUBSCRIBE:
	case UNSUBSCRIBE:
	case SKIP:
	case EXPIRE_MESSAGES:
	case PEEK_MESSAGES:
	case RESET_CURSOR:
	case SET_REPLICATED_SUBSCRIPTION_STATUS:
	isAuthorizedFuture = canConsumeAsync(topicName, role, authData, authData.getSubscription());
	break;
	case TERMINATE:
	case COMPACT:
	case OFFLOAD:
	case UNLOAD:
	case ADD_BUNDLE_RANGE:
	case GET_BUNDLE_RANGE:
	case DELETE_BUNDLE_RANGE:
	return validateTenantAdminAccess(topicName.getTenant(), role, authData);
	default:
	return FutureUtil.failedFuture(
	new IllegalStateException("TopicOperation [" + operation.name() + "] is not supported."));

The purpose of this PR is to support role with consume topic authorization to GET_BACKLOG_SIZE of topic.
