-- Gets a list of tags for the specified AWS CloudHSM cluster.
--
--
-- This is a paginated operation, which means that each response might contain only a subset of all the tags. When the response contains only a subset of tags, it includes a @NextToken@ value. Use this value in a subsequent @ListTags@ request to get more tags. When you receive a response with no @NextToken@ (or an empty or null value), that means there are no more tags to get.
