Task: Migrate risk scanner to the Analyst

[JingChen23]

The risk scanner actually plays the role of Analyst.

It combines the information of the image scanner report and the service configurations of the workloads. Then provide security insights for the workloads.

At first, before we add the db and the Analyst. We can migrate the risk scanner to the resource collector first. At this stage, we can eliminate the cronjobs.

Secondly, when we add the db and involve the Analyst, we can move the logic to Analyst.

At above 2 stages, the risk scanner still send the data to OpenSearch directly.

When data exporter is implement, Analyst (risk scanner logic's new home) will send the data to data exporter to forward the report to OpenSearch or wherever else.
