elastic-agent
elastic-agent-autodiscover library has been updated to version 0.6.4, disabling metadata For kubernetes.deployment and kubernetes.cronjob fields.

Details
The elastic-agent-autodiscover Kubernetes library by default comes with add_resource_metadata.deployment=false and add_resource_metadata.cronjob=false.

Impact
Pods that will be created from deployments or cronjobs will not have the extra metadata field for kubernetes.deployment or kubernetes.cronjob, respectively. This change was made to avoid the memory impact of keeping the feature enabled in big Kubernetes clusters.
