Littlechef-rackspace

* Add "rebuild" and "list-servers" commands
* Display performance flavors better (Samuel Toriel)
* Support creating IAD and HKG public cloud resources
* Add --dry-run argument for showing what arguments
a node will be created with, but not actually executing
the creation.
* Deprecate 'rackspace' section of config.cfg; LittleChef has deprecated
the use of a config.cfg. Future configuration for littlechef-rackspace
should use rackspace.yaml.
* Add template support to creating nodes: templates are groups of arguments
that are specified on the command line after 'create' and should reduce
the boilerplate associated with spinning up a new node.
* BREAKING: Remove 'hostname' argument. Nodes are
created with the same hostname as their API name.
* BREAKING: littlechef 1.6.1 is required. Your littlechef configuration
needs to be specified in littlechef.cfg now (not config.cfg), and you
must have an environments/ directory.

* Support creating SYD resources (if your account has Sydney OpenStack
enabled)

* list-networks command to view custom networks on your account
* create command now takes a networks list
* Fixed regression introduced in 0.4 where not specifying opscode
Chef would not deploy chef on new nodes

* Python 2.6 support
* --skip-opscode-chef and --use-opscode-chef options to allow not using
Opscode Chef Repositories on newly bootstrapped nodes

* --hostname to create node file with specified hostname
* --plugins and --post-plugins for executing plugins before and after chef run

* --environment to create nodes in a specific Chef Environment
* Fixed some errors in configuration parsing
