[2.x] Changed the imagePullSecrets to spec.

[svenvanhees]

Changed the imagePullSecrets to a spec rather than an attribute. The attribute was not placed in the correct yaml position.

For reference:

apiVersion: v1
kind: Pod
metadata:
  name: private-reg
spec:
  containers:
  - name: private-reg-container
    image: <your-private-image>
  imagePullSecrets:
  - name: regcred
