As a part of supporting kubernetes agent instrumentation and observability use cases described here we need to support hints based auto-discovery in agent to bring it in parity with beats. When this is delivered, K8s app authors can declare hints, similar to described in beats documentation metricbeat and filebeat app deployment manifests and then expect agent to pick these hints up and take appropriate action based on the hint.

The hint should be able to reference template to reduce the size of the configuration.
