We need to port
#2281597: Clear external caches (varnish, etc.) →
to 8.x
another similar 7.x module here: https://www.drupal.org/project/clear_varnish_page_cache →
had a look at how to do this.
Depends on which version of varnish in use.
My client currently uses purge and varnish_purger (aka varnish_purge)
would be nice to support both.
