NeuVector: Change all images to Ironbank, update to latest

Since all of the Ironbank images are now available (with one exception) we should change the chart values to use the IB images by default. The one exception to available IB images is the updater image. From some investigation we should be able to use the Big Bang base image in place of the updater since it just runs sleep/curl commands. We should also update the chart to the latest version (supported by the images).

Acceptance criteria:

• All images deployed are Ironbank images
• NeuVector working as expected (it may take some investigation/effort to determine how to deploy on k3d?)
