Update services

[SBlechmann]

removed ${dockerCmd} -> replaced with simple "docker-compose"

docker always threw errors

$ ./services postgres
Stopping running containers
unknown shorthand flag: 'f' in -f
See 'docker --help'.

According to the Docker Documentation docker compose (without the hyphen) is now a valid command, since the docker-compose commands (with the hyphen) have been rolled into the main docker client. The docker client kept pestering users to switch it to docker compose - so I did. The script still supports the olderdocker-compose version if necessary with:

./services start legacy

I think this comes down to the version of docker you are using - could you try the following and compare:

docker -v
Docker version 20.10.12, build e91ed57
docker-compose -v
docker-compose version 1.29.2, build 5becea4c

According to the FIWARE docs to use the docker compose you'll need Docker version 20.10 or higher and Docker Compose 1.29 to use the ./services start directly.
