This hook is enabled for post-delete and pre-upgrade triggers.
The indices deleted by this hook are Kibana's meta indices
  - .kibana
  - .kibana_1
  - .kibana_2
  etc

This is done to get around https://github.com/elastic/kibana/issues/58388
which sometimes prevents Kibana deployments from upgrading successfully.
