InstanceTags

Instance tags

Allow tags (arbitrary key-value pairs) to be attached to instances. These would be similar in functionality to tagging as supported by EC2.

To implement this will require:

• A new database table to keep track of the tags
• Modify the nova api to allow annotating instances with tags (create, delete, describe)
• Modify the EC2 api so that tag-related EC2 calls (e.g., create tags, delete tags, describe tags) work
