K8s collector should only send the data schema defines

The current k8s collector controller would send everything it collects which is not necessary as the database only stores the data based on the schema.

It should send the data defines in the schema only.

Start by locating the K8s collector controller and the database schema it feeds. Compare the data sent by the collector with the fields defined by the schema, then verify that only schema-defined data is emitted and stored.
