Kubernetes runner does not recognize allowed_pull_policies in values.yaml

Summary

The Kubernetes runner can have allowed_pull_policies defined in the values.yaml. When running a job with an allowed_pull_policies the job will fail because the pull_policy in the job defintion is not one of the defined pull policies:

ERROR: Preparation failed: failed to pull image 'registry.gitlab.com/duncan_harris_ultimate_group/cicd-toolbox:latest': pull_policy ([Always]) defined in GitLab pipeline config is not one of the allowed_pull_policies ([])

Steps to reproduce

1. Deploy a Kubernetes runner with allowed_pull_policies set.
2. Attempt to run a job with an image pull_policy defined.

.gitlab-ci.yml

use_image:
  stage: test
  tags: 
    - specific-runner
  image: 
      name: registry.gitlab.com/duncan_harris_ultimate_group/cicd-toolbox:latest
      pull_policy: always
  script:
    - echo "Hello!"

Actual behavior

The job will terminate with a Runner System Error because the defined pull_policy is not in the list of allowed_pull_policies

Expected behavior

The allowed_pull_policy should be applied and used
