Removes unused components from the OpenAPI model.

<p>This plugin will take effect by default, but can be disabled by setting
"openapi.keepUnusedComponents" to true. Refs are removed in rounds until
a round of removals has no effect.

<p>TODO: This plugin currently only supports the removal of schemas and security schemes.
