Update requirements.txt to point to 0.12.4 libcloud
0.7 version
Updated text justification from 10 characters to 20

Performance flavors were added to the rackspace flavors list and
they have a bit more text than the standard flavors. This caused a confusing
looking list like:

7         15GB Standard Instance
8         30GB Standard Instance
performance1-11 GB Performance
performance1-22 GB Performance

Updated it to look like:

7                   15GB Standard Instance
8                   30GB Standard Instance
performance1-1      1 GB Performance
performance1-2      2 GB Performance

Add example configuration YAML file
Parse YAML config file when present, warn that .cfg is deprecated

role you can run

fix-rackspace staging-dfw base --name=web-n01.staging

to bootstrap a new node
Add HKG support
Change name of config.yaml to rackspace.yaml
Allow rackspace.yml if you don't like .yaml files
Don't pass templates to the create command (makes output verbose)
