Also noting that this significantly changes the directory structure that the
metadata shell presents. We have `/local` and `/image`, for example, with
whatever is currently under `/` moving under `/image`. We also have no `data`
directory underneath a topic partition. For example:
`tree /`

Whereas with the current version (there is no `tree` command -- a really
nice addition!)
`ls /`

```
`cat /topics/foo/0/data`

I don't think this is problematic and does not require a KIP, but would like
to confirm.
