Modify Disconnected format

[cooktheryan]

As a fetcher, I would like to match the format below to help make the configuration and management of disconnected hosts easier so we don't have to change the format in the picture.

AC:
Verify we match @sallyom suggestion

disconnected: true
device: /dev/sdb1
images:
  schedule: "*/1 * * * *"
  - name: image2
    imagePath: images/image.tar
  - name: colors 
    imagePath: colors/image.tar
  - name: orange
    imagePath: horsey/image.tar
targetConfigs:
- name: fetchit
  raw:
  - name: raw-ex
    targetPath: examples/raw
    schedule: "*/1 * * * *"
    pullImage: false
  branch: ci```
