Rename stop-orphan-resources to stop-removed-resources and stop-orphan-actions to stop-removed-actions:

• API commits to add constants for the new names
• Add the new names to cluster_options[], moving the old names to alt_name (also replace "orphan" with "removed" in the descriptions)
• API commits to deprecate the old constants
• Update comment, logs, and documentation that refer to the old names
• It would be helpful, though not necessary for this task, to update other uses of "orphan" in comments, logs, etc., where "removed" makes more intuitive sense
• Create a future-series task to drop support for the old names (with an XSL transform) after a suitable amount of time
