Related to: #500 Signed-off-by: Sridhar Gaddam <[email protected]> * Fix flaky error seen while running tests As part of the test framework, when istio and istio-cni namespaces are deleted, we were not waiting until the namespaces are deleted. Because of this, we were seeing some race conditions in subsequent tests. This PR fixes it.
