SPIKE for OSSMDOC-270. SPIKE is completed when we can properly scope OSSMDOC-270 with a user story, AC, and story points.

NetworkPolicy is a feature that breaks networking and the OSSM documentation could explain more clearly what it is and when to create one.

For example, pods in an SMMR registered namespace that don't have auto-injection on will be removed from the network as a result of the operator setting up that namespace, but we don't explain this.

It might be good to add some examples in stating cases where this might need to be added. C
