Given that VersionOverridingElasticsearchContainer has been introduced in 2.3.x only and the upgrade deprecates a constructor of ElasticsearchContainer 2.2.x uses, let's move this upgrade as of that version. We can reconsider if new features are required in 2.2.x.

This version brings a number of deprecations for containers where we have to provide the version of the image. I've found elasticsearch, redis and mongoldb to be affected but others might too. I got tricked by a build cache that didn't exhibit the deprecating warnings so I've decided to revert and reconsider the upgrade later.
