Starting an arangodb cluster using docker-compose

arangodb-cluster.md

This is in response to issue #18900.
It shows how to set up an arangodb cluster with 3 agents, 2 coordinators and 3 db severs, using docker-compose. This is not the way I would set up a cluster in production, but it is ok for testing the cluster functionality. I recommend checking out the official documentation, especially Using the ArangoDB Starter.

To start the cluster, run docker-compose up. Both coordinators can be accessed from the host, on ports 7001 and 7002.

You're right, it was a copy/paste error. It follows the same structure as the other two dbs. I updated the gist accordingly. Thanks for pointing that out!

Thank you @apetenchea it did the job!
