Like the previous commit, we can move this process into zuulv3 and use
ansible.

-Node Ready Scripts
-==================
-
-Each label can specify a ready script with `ready-script`.  This script can be
-used to perform any last minute changes to a node after it has been launched
-but before it is put in the READY state to receive jobs.  In particular, it
-can read the files in /etc/nodepool to perform multi-node related setup.
-
-Those files include:
-
-**/etc/nodepool/role**
-  Either the string ``primary`` or ``sub`` indicating whether this
-  node is the primary (the node added to the target and which will run
-  the job), or a sub-node.
-**/etc/nodepool/node**
-  The IP address of this node.
-**/etc/nodepool/node_private**
-  The private IP address of this node.
-**/etc/nodepool/primary_node**
-  The IP address of the primary node, usable for external access.
-**/etc/nodepool/primary_node_private**
-  The Private IP address of the primary node, for internal communication.
-**/etc/nodepool/sub_nodes**
-  The IP addresses of the sub nodes, one on each line,
-  usable for external access.
-**/etc/nodepool/sub_nodes_private**
-  The Private IP addresses of the sub nodes, one on each line.
-**/etc/nodepool/id_rsa**
-  An OpenSSH private key generated specifically for this node group.
-**/etc/nodepool/id_rsa.pub**
-  The corresponding public key.
-**/etc/nodepool/provider**
-  Information about the provider in a shell-usable form.  This
-  includes the following information:
-
-  **NODEPOOL_PROVIDER**
-    The name of the provider
-  **NODEPOOL_CLOUD**
-    The name of the cloud
-  **NODEPOOL_REGION**
-    The name of the region
-  **NODEPOOL_AZ**
-    The name of the availability zone (if available)
