pillar/top.sls only distributes postgres.auth to manager-class roles,
so sensors / heavynodes / searchnodes / receivers / fleet / idh /
hypervisor / desktop minions never received the postgres telegraf
password they need to write metrics. Broadcasting the aggregate
postgres.auth pillar to every role would leak the so_postgres admin
password and every other minion's cred.
Fan out per-minion credentials into each minion's own pillar file at
/opt/so/saltstack/local/pillar/minions/<id>.sls. That file is already
distributed by pillar/top.sls exclusively to the matching minion via
`- minions.{{ grains.id }}`, so each minion sees only its own
postgres.telegraf.{user,pass} and nothing else.
- salt/postgres/auth.sls: after writing the manager-scoped aggregate
pillar, fan the per-minion creds out via so-yaml.py replace for every
up-minion. Creates the minion pillar file if missing. Requires
postgres_auth_pillar so the manager pillar lands first.
- salt/telegraf/etc/telegraf.conf: consume postgres:telegraf:user and
postgres:telegraf:pass directly from the minion's own pillar instead
of walking postgres:auth:users which isn't visible off the manager.
