directory is a right thing.
Let's keep this in mind as we work on the LogStream
administrative/management side. I think some hierarchy would make sense -- the
notion of a namespace to separate different LogStreams using the same "storage
directory" would be nice (DistributedLog has this concept).
Right now we just have a String (inside of `LogName`) to uniquely identify
one LogStream from another. This was intentional to let us either change how
`LogName`s compute uniqueness, or overlay some "logical" hierarchy using that
arbitrary String.
