Next version is 2014.2.1.

pbr pre-versioning causes current sdist to have versions leading up to
2014.1.0, but that is a release in the past...  already released - we
should be leading up to 2014.2, but solum already has a tag of
2014.2.0 (which is equivalent to 2014.2) so we need to increment the
minor version getting 2014.2.1.
