Crash on import (Windows)

[Daniel Goldberg]

Python 2.7 64-bit Windows, initial import leads to

```
c:\python27\lib\site-packages\hnvclient\__init__.py in <module>()
     15
     16 __version__ = pbr.version.VersionInfo(
---> 17 'hnvclient').version_string()
     18
     19 CONFIG = {
```

Final error is
`Exception: Versioning for this project requires either an sdist tarball, or access to an upstream git repository. It's also possible that there is a mismatch between the package name in setup.cfg and the argument given to pbr.version.VersionInfo. Project name hnvclient was given, but was not able to be found.`

Solved by giving the project name as python-hnvclient
