> While working on HDFS-1073 I continually found it inconvenient that StorageDirectory
is a non-static inner class of Storage. This makes testing more complicated, and also has
unintuitive results, like {{sd.read()}} having side effects on a Storage object.
> I'd like to try to make it a static inner class so that these side effects are clearer
and it's easier to use in isolation.
