chore: add new config to control the pull behaviour for verify

[renzodavid9]

Fixes: #9148

Description
This PR adds a new config field for local verify test cases to force the use of a local image if one exists, if it doesn't exists it will trigger a pull.

How to test the change
With the following skaffold.yaml file:

apiVersion: skaffold/v4beta8
kind: Config
verify:
- name: with-local-img
  executionMode:
    local:
      useLocalImages: true
  container:
    name: gcloud
    image: gcr.io/cloud-builders/gcloud:latest
    command: ["/bin/bash"]
    args: ["-c", "gcloud version"]

Execute skaffold verify. You'll notice that the image is pull from the registry before running the container. Now if you run skaffold verify again, you'll see that Skaffold is not trying to pull the image again from the registry.
