Entity Tag as a Template Variable in CQL

Using CQL, you can reference the variable tag to match an entity tag (x-cortex-tag) in a dynamic scorecard rule.  For example, if you're trying to confirm that a key in a key:value pair in custom data matches an entity tag:

custom("my-key") = tag

You can also access the service yaml with entity_descriptor, such as entity_descriptor.info.{{x-cortex-tag}}.
