Description of problem: When traffic is tested immediately after the creation of a multinetworkpolicy the test is flaky. The multus-networkpolicy operator takes up to second to push the policy to the pods. This causes flaky test results. A work around is to use Eventually(...) on the first test case.

Version-Release number of selected component (if applicable):

How reproducible: Easily

Steps to Reproduce:
1. Deploy cluster 
2. Run policy eco-gotests test cases
3.
Actual results: Flaky test results

Expected results: Test cases to pass or fail consistently.

Additional info: A test fix will be created by adding a sleep or Eventually(...) on the first test case. This gives enough time for the operator to push the policy to all the pods.
