[ElasticSearch] unable to build docker image without ES node

[insekticid]

When building docker image and using Elasticsearch mapping, composer run-script --no-dev post-install-cmd will trigger in php bin/console cache:clear and it will try to connect to ElasticSearch and get indexes, so docker build will end with: No alive nodes found in your cluster

in CI you do not have access to other services, so this is bad behaviour
