docker: adds Elastic licensed 8.11.3 test image (#3664)

This adds an image tagged as elasticsearch8 which is based on our Java
base layer, similar to elasticsearch7 except aspects specific to
Elasticsearch 8.x.

Notably, Elasticsearch 8.x requires a launcher process, and defines Java
options as ES_JAVA_OPTS. Similar to 7.x Elastic requires modules not in
our JRE image, so we use the full one instead.

Note: As this is a test image, not a production image, usage should not
violate the Elastic Basic license developers typically use, and is the
default.

+## zipkin-elasticsearch8 Docker image
+
+The `zipkin-elasticsearch8` testing image runs Elasticsearch 8.x for [Elasticsearch storage](../../../zipkin-storage/elasticsearch)
+integration.
+
+To build `openzipkin/zipkin-elasticsearch8:test`, from the top-level of the repository, run:
+```bash
+$ DOCKER_FILE=docker/test-images/zipkin-elasticsearch8/Dockerfile build-bin/docker/docker_build openzipkin/zipkin-elasticsearch8:test
+```
+
+You can use the env variable `ES_JAVA_OPTS` to change settings such as heap size for Elasticsearch.
+
+#### Host setup
+
+Elasticsearch is [strict](https://github.com/docker-library/docs/tree/master/elasticsearch#host-setup)
+about virtual memory. You will need to adjust accordingly (especially if you notice Elasticsearch crash!)
+
+```bash
+# If docker is running on your host machine, adjust the kernel setting directly
+$ sudo sysctl -w vm.max_map_count=262144
+
+# If using docker-machine/Docker Toolbox/Boot2Docker, remotely adjust the same
+$ docker-machine ssh default "sudo sysctl -w vm.max_map_count=262144"
+
+# If using colima, it is similar as well
+$ colima ssh "sudo sysctl -w vm.max_map_count=262144"
+```
+
+#### License
+
+This Elasticsearch image is only made for testing features supported by Zipkin,
+and is subject to [Elastic-License-2.0](https://www.elastic.co/licensing/elastic-license).
+For more details, inspect the LICENSE.txt and NOTICE.txt in the /elasticsearch
+directory of this image.
