This pre-release of Toil contains bug fixes and the addition of experimental, CGCloud-based auto-scaling.

https://github.com/BD2KGenomics/toil/milestone/17?closed=1

Due to the experimental nature of the auto-scaling feature, we decided to skip publishing a stable release for it. To install this release with pip, use `pip install toil==3.4.0a1.dev228`.

The next stable release of Toil will contain docker-based autoscaling for EC2.

- Fix: Toil fails completely when not installed with [aws] extra (1115)
- Prevent virtualenv from silently upgrading pip and setuptools, potentially breaking build (1270)

Core production is advised to skip this release.
