Bug 1643301

Cause: The Automation Broker always created a network policy to give the transient namespace access to the target namespace. Consequence: Adding a network policy to a namespace that does not have any other network policies in place causes the namespace to be locked down to the newly created policy. Before the network policy, everything was open and namespaces could communicate with each other. Fix: The Automation Broker looks to see if there are any network policies in place for the target namespace. If there are none, the broker will not create a new network policy. The broker will assume that things are open enough to allow the transient namespace we create to communicate with the target namespace. The broker will still create a network policy giving the transient namespace access to the target namespace, if there are other network policies in place for the target namespace. Result: The fix allows the broker to perform the APB actions without affecting existing services running on the target namespace.
