Updating Eclipse Ditto

First, kill all docker containers. Then remove them, and remove their related images:

docker kill $(docker ps -q)
docker rm $(docker ps -a -q)
docker rmi $(docker images -q)

Then we get the latest version of the docker-compose from GitHub:

wget https://github.com/eclipse/ditto/archive/refs/heads/master.zip
unzip master.zip

Unzip it, browse to the right directory, and start it:

cd master/deployment/docker
docker-compose up -d
