[Swiftstack] Add checkbox to settings UI to disable upload_cirros task

[Stanislav Kolenkin]

The upload_cirros task tries to upload image at the end deployment.
This leads to failed deployment.
You should add the following code to environment_config.yaml in plugin.
  upload_cirros_test:
    weight: 20
    type: "checkbox"
    value: true
    label: "Enable upload test"
    description: "Upload cirros base image when the depoloyment is done"

And add puppet manifests for skipping this task.
