If name is not given, it will generate a random name using
prefix. The node name is added to the global substitution
map, which is used to parameterize templates in scripts
containing the form {variable_name}.
The list of bundle names is concatenated with any globally
common bundle names from which result the set of files to be
installed, and scripts to be run on the new node.
The pubkey is concatented with any other public keys loaded
during configuration and used as the first step in the
multi-step deployment. Additional steps represent the scripts
to be run.
The image_name is used to determine which set of default
bundles to install, as well as to actually get the image id in
deploy()."""
