Streamline launching new nodes.
* launch/README: More clarity on Jenkins slave example, and additional levels of cut-n-pasteability on the DNS record creation example. Also switch from requiring root to expecting to be run from a normal account with sudo access and membership in the puppet group. * launch/launch-node.py: Default to assuming the certname is the same as the node FQDN, if it isn't overridden via command-line option.
