update docs on how to set up rootless docker access

* [ ] Prefix every docker and docker-compose command in Rakefile with sudo to allow running rake commands as a normal user.

* Makes the entire rake command not enforce root on other subcommands which might not need it. * Makes leftover files to not be root-owned. Easier to cleanup. * Prevents the command to fail mid-way if you forgot to sudo it. Which then leaves the user wondering if they can continue with sudo or if they should clean up the artifacts created so far and start over.

UPDATE: will update the docs how to set up docker, so it doesn't require root access.
