 Provisions a new server in the Amazon EC2 and then perform a Chef bootstrap (using the SSH protocol).

The main assumption is a baseline OS installation exists (provided by the provisioning). It is primarily intended for Chef Client systems that talk to a Chef server.  By default the server is bootstrapped using the {ubuntu10.04-gems}[https://github.com/opscode/chef/blob/master/chef/lib/chef/knife/bootstrap/ubuntu10.04-gems.erb] template.  This can be overridden using the <tt>-d</tt> or <tt>--template-file</tt> command options.
