`deploy create` requires `--stack` (deploy.py:70) and lives in the
`deploy` group, not `deployment`. `laconic-so deployment create ...`
does not exist as a subcommand.
`host-metrics` is a native stack -- spec.yml and `laconic-so --stack`
both take the bare stack name, not a path. Replace the `docker ps -qf`
filter with `laconic-so deployment --dir ... logs` so the verify
recipe works regardless of the laconic deployment-hash prefix on the
container name.
