account server metadata are not stored in memcache

[Chmouel Boudjnah]

currently metadata for container are stored in memcache but not for account. Only status and container_count, making available metadata for account server would make middleware able to use it and not having to recreate them in another memcache space.

    Account and container info fixes and improvement.

    - Fixes bug 1119282.
    - Allow middleware accessing metadata of an account without having to
      store it separately in a new memcache namespace.
    - Add tests for get_container_info that was previously missed.
    - Add get_account_info method based on get_container_info, a function
      for other middleware to query accounts.
    - Rename container_info['count'] as container_info['object_count'].
