Subscribe to ConfigRevertInterface::REVERT event

Problem/Motivation

The Configuration Update Base (config_update) module, part of the Configuration Update Manager package, provides a method to revert a configuration item to its currently provided state. A ConfigRevertInterface::REVERT event is dispatched when an item is reverted.

If a rewrite is present, likely the expected outcome is that the rewrite is reapplied when a revert occurs.

Proposed resolution

Subscribe to ConfigRevertInterface::REVERT event, reapplying any rewrites for the given item.

Remaining tasks

User interface changes

API changes

Data model changes
