Minimum Agent Versions

Are there minimum versions of the Datadog Agent and/or Cluster Agent required?

• Agent: vX.Y.Z
• Cluster Agent: vX.Y.Z

Describe your test plan

• Run the bundle command make VERSION=X.Y.Z LATEST_VERSION=X.Y.Z bundle and check that the DD_TOOL_VERSION env var is in the bundle and bundle-community-operators clusterserviceversion files. The bundle's value should be redhat. The bundle-community-operators's value should be operatorhub
• Run make bundle-redhat (X.Y.Z must be an existing image tag in the redhat registry) and check that the DD_TOOL_VERSION env var is present in the bundle-redhat and bundle-redhat-marketplace csv files with value redhat
