fs: Break fs package to top-level and introduce ObjectAPI interface. ObjectAPI interface brings in changes needed for XL ObjectAPI layer. The new interface for any ObjectAPI layer is as below ``` // ObjectAPI interface. type ObjectAPI interface { // Bucket resource API. DeleteBucket(bucket string) *probe.Error ListBuckets() ([]BucketInfo, *probe.Error) MakeBucket(bucket string) *probe.Error GetBucketInfo(bucket string) (BucketInfo, *probe.Error) // Bucket query API.
