[backport 8.10] Elastic-agent-autodiscover to v0.6.4

[gizas]

• Breaking change

What does this PR do?

WHAT: Update the Elastic-agent-autodiscover to v0.6.4. This disables by default metadata enrichment for deployment and cronjobs
WHY: The metadata enrichemnt for replicasets (which are produced from deployments) and cronjobs is proved a feature with heavy memory usage especially in big kubernetes clusters. The outcome was to enhance pods that were created from deployments and cronjobs with the relevant deployment/cronjob name. Decision

Why is it important?

We want to avoid the memory impact of keeping the feature enabled in big k8s clusters

@cmacknz can I merge this as only vulncheck fails?

@pierrehilbert, @cmacknz I have retried the test but still fails. It is the elastic-agent build so I am reluctant to merge. Can you have a look please?

Looks good to go this time.

Can you please make it at least configurable? We use kubernetes.deployment do distinguish between pod types while configuring elastic-agent. Hint based discovery is still limited so we rely on condition based.
