Review comment:
Actually, this may appear counter-intuitive for users especially when Drill
supports `SELECT` with leading slash (see
[DRILL-1130](https://issues.apache.org/jira/browse/DRILL-1130)). When a table
is created and its name does start with '/' it will be created within
workspace, i.e. will be rooted from the workspace.
You could think of it as if you performed `touch` (on Unix[-like] OS) to
create a file: `touch /${filename}` and `touch ${filename}` should create a
file in the same directory when working directory (workspace) is root ('/').
