REST API delete requests for Maven components can have slow performance

If you delete a maven component via REST API it triggers a synchronous rebuild of the affected maven-metdata.xml files. See below stack trace for an example. This can be a very slow operation if the GA or GAV contains a large number of versions to process. We should change this operation to use the lazy rebuild mechanism implemented in NEXUS-23396.
