add run subcommand

I may have missed the feature, but what I'm missing is an equivalent to docker compose run. My setup is a Postgres container that I start in the background (container-compose up -d postgres) and then a flyway container that I run as a one-off command, not in a detached state, but I wait until it exits to know the migration went through without problems. Currently, when I use container-compose up flyway, it will not exit after the command finishes.

Yes. That is just an artifact of how it currently handles tailing container log output. Apologies if it confused you.
