[Swiftstack] User may not want to enable Swift as backend for Glance.

[Stanislav Kolenkin]

Plugin always enables swift as backend for glance, but user may not want to enable Swift as backend for Glance.
This leads to rewritten configuration files.

Possible solution could look like:
Add extra UI checkbox for switching between these options. The following lines should be added into
environment_config.yaml
  swift_as_glance_backend:
    weight: 20
    type: "checkbox"
    value: false
    label: "Use Swift as Glance backend"
    description: "Config Glance backend storage to Swift cluster"
    restrictions:
      - condition: "settings:storage.images_ceph.value == true"
        action: disable

And add puppet manifest for processing these options.
