Rough script for creating jmeter slaves with the rackspace uk cloud api
Scripts:
* setup.py creates cloud instances,installs and starts jmeter-server
* cleanup.py destroys cloud instances who's name matches a pattern
Usage:
1) edit setup.py, and insert your username/api key/ssh keys. Define the number of instances you want
1a) install the dependencies listed at the top of setup.py
2) run setup.py
3) edit jmeter.properties and add the line specified at the end of setup.py's output
4) run jmeter, build a test plan, and start on all remotes.
