  either due to a change in NetworkPolicies or if the relevant labels of the namespaces/pods selected by the
  policy (both subject and peers) are changed in the middle of an existing connection - it is
  implementation defined as to whether the change will take effect for that existing connection or not.
  Example: A policy is created that leads to denying a previously allowed connection, the underlying network plugin
  implementation is responsible for defining if that new policy will close the existing connections or not.
  It is recommended not to modify policies/pods/namespaces in ways that might affect existing connections.What's nextSee the Declare Network Policy
