Takashi Kajinami 4a4bd9c06a overcloud: Remove logic for unsupported old releases 
This change removes logic for releases older than train, because these
releases are already EOLed. This covers only overcloud-* roles and
playbooks and the other items will be covered by separate changes.

Note that this change also removes the containerized_* variables
because current active releases(>=Train) no longer supports
non-containerized deployment. The containerized_overcloud_upgrade
variable is still left because the variable is still required by
the tripleo-ci-base-multinode-standard job template.

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 an 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
