Rackspace CLI - Install the binary with a script

[davecanderson]

The Rackpsace CLI Installation and Configuration documentation includes a Powershell script to download and install the binary but this has the wrong -Uri parameter value.

Also the $DownloadPath variable is not used in all the correct places so changing the value assignment breaks the script. Better to provide the installation path as a parameter.
