This change only affects development environments using Docker.

We have changed the default set up for ElasticSearch in environments using Docker. In particular, ElasticSearch 7 is now no longer supported and the container is no longer built / run. And the ElasticSearch 2 container is now running on port 9200 (previously 6200).

It is recommended that anyone who was on ES7 switch back to ES2. If you were using ES7 (check `settings.ELASTICSEARCH_MAJOR_VERSION`) then you should change `ELASTICSEARCH_MAJOR_VERSION` to 2 and rebuild your elasticsearch databases (`./manage.py ptop_preindex`) against ES2.

If you were already using ES2, then you may need to change `ELASTICSEARCH_PORT` to `9200` (from `6200`) if you were using Docker.
