Get es_opts faster in docker-entrypoint.sh #233

I use ES on k8s 1.11, and there are many Services in the same namespace. When a container is started, environment variables related with Services are injected. (https://kubernetes.io/docs/concepts/services-networking/service/#discovering-services)

Problem is, if there are many env vars, iteration for es_opts takes several minutes. It seems that read is especially slow. So, in this PR it filters environment variables before iteration.

Maintenance of the docker files for elasticsearch has moved to the elasticsearch repo. As we will be archiving this repository, I am going to close this PR. If you are still interested in making this contribution, please open a new pull request there.
