Why is this one and SVC_PATH still at /?

Good point, I'll see if I can clarify the docs or make all these paths relative. There are some paths that are used at runtime which will never make sense with an FS_ROOT set. That's why it was a piecemeal change

👏 I wonder if we could use this for integration testing as well?

This change lays the groundwork for replacing `hab-bpm`, namely in its
role setting up Studios. When using the `hab` binary on installation, if
an `$FS_ROOT` environment variable is set, this will effectively replace
the default `/` path, which allows a user or some automation to install
into a mounted filesystem or subdirectory that will become the root of a
filesystem for Habitat.
For example, here we install `core/redis`, its dependencies, any
downloaded public origin keys, and downloaded artifacts under a
`/tmp/newfs` filesystem root:
```
> ls -l /tmp/newfs
ls: cannot access /tmp/newfs: No such file or directory
> env FS_ROOT=/tmp/newfs ./target/debug/hab install core/redis
