K Jonathan Harker 726c00c541 Add path to installing puppet 3 on nodepool nodes
Instead of looking for an argument, change the install_puppet.sh script
to look for an environment variable to switch to installing puppet3.
Also export this environment variable in prepare_node.sh (albeit with a
default value that does not install puppet3).
