Warning

I noticed that for test resources ibm_resource_instance.resource_instance_activity_tracker_7day_no_usage, ibm_resource_instance.resource_instance_logdna_7day_no_usage, ibm_resource_instance.resource_instance_monitoring_graduated_no_usage, ibm_resource_instance.wml_instance_standard some or all units show: "Monthly cost depends on usage: ...".

We'll need to address that in a future PR. Might just be a matter of adjusting the units used.
