mirroring needs a parameters_json with a structure like this, so that cluster provisioning will come with additional workerpool and mirrormaker application running on it.
source_crn, source_alias, and target_alias are user input and required.

parameters_json = jsonencode(
    {
      mirroring = {
        source_crn   = data.ibm_resource_instance.es_instance_source.id
        source_alias = "source-alias"
        target_alias = "target-alias"
        }
     }
 )

user also has the options to configure it to be more complex like below:

parameters_json = jsonencode(
   {
     mirroring = {
       source_crn   = data.ibm_resource_instance.es_instance_source.id
       source_alias = "source-alias"
       target_alias = "target-alias"
       options = {
         topic_name_transform = {
            type = "rename" 
            rename = {
              add_prefix = "add_prefix"
              add_suffix = "add_suffix"
              remove_prefix = "remove_prefix"
              remove_suffix = "remove_suffix"
            }
         }
         group_id_transform = {
           type = "rename" 
           rename = {
             add_prefix = "add_prefix"
             add_suffix = "add_suffix"
             remove_prefix = "remove_prefix"
             remove_suffix = "remove_suffix"
           }
         }
       }
     }
   }
 )

Note, you need plan = "enterprise-3nodes-2tb" to use mirroring, but provisioning of an enterprise instance can take two to three hours. You probably do not want to test that in pr_test.go.

Addressing changes with the latest stable provider release https://registry.terraform.io/providers/IBM-Cloud/ibm/1.71.0

@Ak-sky
the resource ibm_event_streams_mirroring_config depends on the provider release v1.71.0, the parameters_json for mirroring does not, it is already supported by resource controller and Event Streams' service broker.
