example telegraf scraping config

Posting it here as it affects all stabilizer/stabilizer-fls/booster/thermostat-mqtt/thermostat-eem.

This should be integrated into the docs to give people a head start. Also IMO the common docs that are more miniconf-specific from both booster and stabilizer should both be replaced with and reference to miniconf docs.

/etc/telegraf/telegraf.d/miniconf-telemetry.conf

[[inputs.mqtt_consumer]]
  servers = ["tcp://mqtt:1883"]
  topics = [
    "dt/sinara/dual-iir/+/telemetry",
    "dt/sinara/lockin/+/telemetry",
  ]
  data_format = "json"
