Migrating image_info module from AnsibleModule to OpenStackModule

1. Added ImageInfoModule class
2. Added basic test to see if image_info reflects created image and deletion of image
3. Added deprecated_names
4. Added 'type'/'required' in argument_spec
5. Removed debug statements from test as we are checking already with image_info module
