KEDA - v2.7.0

We are happy to release KEDA 2.7.0 🎉

Here are some highlights:

• Introduction of pausing autoscaling through annotations for ScaledObject.
• Introduce ARM-based container image
• Introduction of AWS DynamoDB, Azure Data Explorer, GCP Stackdriver & GCP Storage scalers
• Introduction of Azure Key Vault as trigger authentication provider
• KEDA is secure-by-default and runs as non-root
• Support for non-public Microsoft Azure clouds
• 19 new contributors
• Deprecation of metadata.type is deprecated in favor of the global metricType for CPU, Memory, Datadog scalers (GitHub Discussion)
