refactor(docker-dev): set up elasticsearch using local mapping on docker-compose.dev

[dexter-mh-lee]

Make it easy to test mapping/setting.json changes by adding an elasticsearch-setup:debug image to docker-compose.dev.yml

The overridden elasticsearch-setup container mounts the local mapping/setting.json files and uses them to create indices.
Followed the method used in the dev setup for gms/mae-consumer/mce-consumer containers

Test
./docker/dev.sh runs correctly and confirmed that the local changes to mappings got picked up
Running the prod path by doing the following (Thanks @jplaisted)

cd docker
./nuke.sh # start from scratch to really verify things
docker compose pull # pull latest images
docker image rm docker_elasticsearch-setup # delete pulled image
docker-compose build elasticsearch-setup # rebuild image
docker-compose -p datahub up # launch docker without pulling

ran correctly as well.

Good catch that we didn't have a developer flow for for this. Agree with the change, so long as we can verify both the "dev" and "prod" docker images work as expected.

Edit: github erased my review comment, give me a second to retype it. Some bad UX here :|
