-1 as this fix breaks the observer entry point entirely and produces an sdist 
that is invalid

```
(observer.venv)~aurora git aurora/. 36700    
% pip install -f dist apache.thermos.observer --pre                   
You are using pip version 6.1.1, however version 7.1.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting apache.thermos.observer
  Could not find a version that satisfies the requirement 
apache.thermos.observer (from versions: 0.10.0-SNAPSHOT)
  No matching distribution found for apache.thermos.observer
```

so pants writes this sdist with a dependency on itself

since it's already broken I'd suggest removing the entry point entirely (so 
we're not advertising a feature we don't actually have).
