Add automated security scan

Build restic from source in Dockerfile

The Docker image restic/restic does not use the latest Alpine image by default. Compiling the binary from source and using a version-tracked Alpine image should address that. The relevant documentation can be found here.

Set up GitHub action to build and test Docker images

Add detailed help for commands

Fix build error on ubuntu 20.04

The generated docker-compose file has an invalid CPU value, crashing the build runner on GitHub. Below YML is an extract.

    deploy:
      resources:
        limits:
          cpus: '^A'
          memory: 100M
        reservations:
          cpus: '0.05'
          memory: 6M

The offending code is most likely caused by generate_config() in dbm.sh:

generate_config() {
    [ "${command}" = 'dev' ] && base_cmd="${DOCKER_RUN} ${docker_dev}" || 
        base_cmd="${DOCKER_RUN} ${docker_prod}"
    # fix incorrect CPU value (see https://github.com/docker/compose/issues/7771)
    cmd="${base_cmd} config | sed -E \"s/cpus: ([0-9\\.]+)/cpus: '\\1'/\""

    # replace tag if applicable
    if [ -n "${tag}" ]; then
        escaped_tag=$(escape_string "${tag}")
        cmd="${cmd} | sed -E 's|^    image: .*|    image: ${escaped_tag}|g'"
    fi

    echo "${cmd}"
}
