Remove container_names from docker-compose.sample.yml

[NickBusey]

Description

This removes the container_name lines from the sample docker-compose file.

When using the docker-compose file on a server with many other docker containers running, finding the mailserver related containers is a pain.

Fixes

Removing the container_name line changes the container names from mariadb and redis etc. to mailserver_mariadb_1 and mailserver_redis_1

This allows much easier inspection of the containers via docker ps | grep mailserver

It is also just better practice I feel like in general. Using the name mariadb locks it down for the whole server.
