Simplify docker compose commands

[ruddyscent]

Since remote and sbc containers run on different machines, it is necessary to separate docker-compose.yml and Dockerfile. However, this makes it cumbersome to specify the related docker-compose configuration file or service name every time you run the docker compose command. Therefore, you should simplify the command by placing these configurations in separate directories.

For example, the configuration files related to the foxy remote will be placed at

./foxy/remote/

and those for the foxy sbc will be placed at

./foxy/sbc/
