Add healthcheck commands to docker-compose.yml (#9143)
This will allow Docker to be automatically check the health of services.
Docker won't do anything other than showing the state in the output of
"docker-compose ps" by default, but some management tools may watch for
container health events.
Here's what my local instance looks like right now:
Name Command State Ports

mastodon_db_1 docker-entrypoint.sh postgres Up (healthy)
mastodon_es_1 /usr/local/bin/docker-entr ... Up (healthy)
mastodon_redis_1 docker-entrypoint.sh redis ... Up (healthy)
mastodon_redis_cache_1 docker-entrypoint.sh redis ... Up (healthy)
mastodon_sidekiq_1 /sbin/tini -- bundle exec ... Up 3000/tcp, 4000/tcp
mastodon_streaming_1 /sbin/tini -- yarn start Up (healthy) 3000/tcp, 127.0.0.1:4000->4000/tcp
mastodon_web_1 /sbin/tini -- bash -c rm - ... Up (healthy) 127.0.0.1:3000->3000/tcp, 4000/tcp
