> In the class Named AclCommand,configure SimpleAclAuthorizer,but no need call loadCache.
> now we have 20,000 topics in kafka cluster,everytime I run AclCommand,all these topics's Alcs need to be authed, it will be very slow.
> The purpose of this optimization is：we can choose to not load the acl of all topics into memory, mainly for adding and deleting permissions.
> PR Available here: [https://github.com/apache/kafka/pull/7706]
> mainly for adding and deleting permissions,we can choose to not load the acl of all topics into memory,then we can add two args "--load-acl-cache" "false" in AclCommand.main;else you don't add these args, it will load the acl cache defaultly.
> we can choose improve the running time from minutes to less than one second.
