Update image for new sdk

- Use proxy layer where possible
  - Image upload has some tricky logic so that stays in the cloud layer
- Convert return value to dict
- Document return values
- Update visibility logic for glance v2 api
- Increase test coverage
- General refactoring to bring more in line with rest of collection
- Deprecate is_public attribute which has been replaced with
  visibility.
- Deprecate volume attribute which has been made obsolete with
  openstack.cloud.volume module. Removed examples showing the volume
  attribute since users are encouraged to use openstack.cloud.volume
  module.
