Swap the ~150-line Python implementation for a 48-line bash script that
delegates YAML mutation to so-yaml.py — the same helper so-minion and
soup already use. Same semantics: seed the creds pillar on first use,
idempotent add, silent remove.
SO minion ids are dot-free by construction (setup/so-functions:1884
strips everything after the first '.'), so using the raw id as the
so-yaml.py key path is safe.
