Fix GetPodLogs failures in NetworkPolicy e2e tests

Browse Source 
GetPodLogs always fails when the tests fail, which is because the tests
specify wrong container names when getting logs.

When creating a client Pod, it specifies "<podName>-container" as
container name and "<podName>-" as Pod GenerateName. For instance,
podName "client-a" will result in "client-a-container" as the container
name and "client-a-vx5sv" as the actual Pod name, but it always uses the
actual Pod name to construct the container name when getting logs, e.g.
"client-a-vx5sv-container".

This patch fixes it by specifying the same static container name when
creating Pod and getting logs.
