Standard for object-storage

[anjastrunk]

Object-storage is one mandatory service in SCS infrastructure, see #587. However, requirements for object-store are not yet defined. Similar to block storage, as an IaaS user, I want to know what capabilities a SCS object-store has. These capabilities include (on exhaustive list)

• API endpoint, as Object storage comes with two different APIs: S3 and Swift.
• Backup/Fail Safe capabilities
• Locality, region, availability zone

The idea was that #587 standardizes APIs, and in the case of object storage, we decided to make the S3 API mandatory and the Swift API recommended.

You are right and we have to standardize capabilities of components behind the API.
