Mike Reeves 05f6503d61 Gate postgres telegraf fan-out on reactor-provided minion id
postgres.auth was running an `unless` shell check per up-minion on every
manager highstate, even when nothing had changed — N fork+python starts
of so-yaml.py add up on large grids. The work is only needed when a
specific minion's key is accepted.

- salt/postgres/auth.sls: fan out only when postgres_fanout_minion
  pillar is set (targets that single minion). Manager highstates with
  no pillar take a zero-N code path.
- salt/reactor/telegraf_user_sync.sls: re-pass the accepted minion id
  as postgres_fanout_minion to the orch.
- salt/orch/telegraf_postgres_sync.sls: forward the pillar to the
  salt.state invocation so the state render sees it.
- salt/manager/tools/sbin/soup: for the one-time 3.1.0 backfill, drop
  the per-minion state.apply and do an in-shell loop over the minion
  pillar files using so-yaml.py directly. Skips minions that already
  have postgres.telegraf.user set.

Mike Reeves 72105f1f2f Drop telegraf push from new-minion orch; highstate covers it
New minions run highstate as part of onboarding, which already applies
the telegraf state with the fresh pillar entry we just wrote. Pushing
telegraf a second time from the reactor is redundant.

- Remove the MINION-scoped salt.state block from the orch; keep only
  the manager-side postgres.auth + postgres.telegraf_users provisioning.
- Stop passing minion_id as pillar in the reactor; the orch doesn't
  reference it anymore.

Mike Reeves ee89b78751 Fire telegraf user sync on salt/key accept, not salt/auth
salt/auth fires on every minion authentication — including every minion
restart and every master restart — so the reactor was re-running the
postgres.auth + postgres.telegraf_users + telegraf orchestration for
every already-accepted minion on every reconnect. The underlying states
are idempotent, so this was wasted work and log noise, not a correctness
issue.

Switch the subscription to salt/key, which fires only when the master
actually changes a key's state (accept / reject / delete). Match the
pattern used by salt/reactor/check_hypervisor.sls (registered in
salt/salt/cloud/reactor_config_hypervisor.sls) and add the result==True
guard so half-failed key operations don't trigger the orchestration.

Mike Reeves cefbe01333 Add telegraf_output selector for InfluxDB/Postgres dual-write
Introduces global.telegraf_output (INFLUXDB|POSTGRES|BOTH, default BOTH)
so Telegraf can write metrics to Postgres alongside or instead of
InfluxDB. Each minion authenticates with its own so_telegraf_<minion>
role and writes to a matching schema inside a shared so_telegraf
database, keeping blast radius per-credential to that minion's data.

- Per-minion credentials auto-generated and persisted in postgres/auth.sls
- postgres/telegraf_users.sls reconciles roles/schemas on every apply
- Firewall opens 5432 only to minion hostgroups when Postgres output is active
- Reactor on salt/auth + orch/telegraf_postgres_sync.sls provision new
  minions automatically on key accept
- soup post_to_3.1.0 backfills users for existing minions on upgrade
- so-show-stats prints latest CPU/mem/disk/load per minion for sanity checks
- so-telegraf-trim + nightly cron prune rows older than
  postgres.telegraf.retention_days (default 14)
