Problem statement

#1700 handled NetworkPolicy changes for KO 2.0 milestone.

To achieve the milestone in a timely manner, a shortcut has been performed to skip the assertions in integration suite about the NetworkPolicy management.

This issue tracks the introduction of a mechanism of network intercepts (like the one from telepresence: https://www.getambassador.io/docs/telepresence/latest/reference/intercepts) and re adding the assertions for NetworkPolicy resources managed by the operator

Acceptance criteria

• Assertions for NetworkPolicy resources managed by the operator are added in the integration tests suite.
