Add annotation to namespace if network policy is assigned automatically

[CodeClinch]

If a namespace does not have an annotation that specifies a network policy the system should add the default network policy and adds the annotation.

• [x] what is the best way to add this annotation (webhook or reconciler for networkpolicy namespace)
• [x] Implementation

Wouldn't it be better to annotate the network policy resource with the source of the security setting?

[CodeClinch]

You are right. It fits better to the network policy.

Should be solved in #179.
