starting services results in error unknown short flag '-c' and more

[gitqlt]

docker-compose.yml uses outdated/incompatible service command-line syntax, like -config.file=/etc/prometheus/prometheus.yml better: --config.file=/etc/prometheus/prometheus.yml

or -collector.procfs=/host/proc better: --path.procfs=/host/proc

and some more corrections like the above are needed on Ubuntu18 Linux to start the services.
