use docker compose lib instead of cli

• Create a Project struct - example: https://github.com/docker/libcompose#usage
• Then the project has the needed commands (build / up / down / kill) - docs: https://godoc.org/github.com/docker/libcompose/project

Blocking on docker/libcompose#474 since we are using docker compose version 3

Closing for now. We can revisit once libcompose supports docker v3
