* add "cachable: true" to set_fact calls when the fact would be used by other roles in later runs; the other fact names were checked to make sure they are not referred to in other roles * consolidate the formatting of the set_fact calls, using the proper yaml structure instead of `set_fact: foo=bar` Depends-On: I987d51cc252b7ebc3972d60497234fa676864882 Change-Id: I5dd3084ead618e357b1e7d841ea2ee794bd0569a |

Role Name
An Ansible role for scaling and deleting nodes from an overcloud.
Requirements
This role assumes it will be executed against a host on which a Liberty, Mitaka, Newton, or Ocata under/overcloud have already been deployed.
Note: The validate-simple role must be accessible.
Role Variables
A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
Note: Make sure to include all environment file and options from your initial Overcloud creation. This includes the same scale parameters for non-Compute nodes.
- artosn_scale_nodes: -- boolean value that will scale nodes if true
- artosn_delete_original_node: -- boolean value that will delete the original node of type that was scaled
