(#1409) Modify scope-pod-extract initContainer
79a1ce2 
- modify "imagePullPolicy": "IfNotPresent" for `scope-pod-extract`
- this fix would allow to avoid `ImagePullBackOff` status for
  Application pod in following scenario:
  - step 1 we preload the application image into cluster
  - step 2we deploy `scope k8s`
  - step 3we deploy application container
- This commit will modify `scope-pod-extract` behavior
  to use the image which was preloaded in step 1) instead of
  pulling the image from non-existent location

Fixes: #1409
