Influxdb3 output health-check

[andrgras]

Influxdb3 is available for some time, today I tried to use it and getting errors on health check
If I remove health-check-period then everything works.

From documentation system token is needed
https://docs.influxdata.com/influxdb3/enterprise/admin/tokens/resource/create/#create-a-system-token

Then u can use
curl http://localhost:8181/health --header "Authorization: Bearer apiv3_token"
OK

outputs:
  influxdb-output:
    type: influxdb
    url: http://10.81.138.10:8181
    bucket: telemetry
    token: apiv3_tokenxxxxxxxxxxxxxxxxxxx
    batch-size: 1000
    flush-timer: 10s
    health-check-period: 60s
    event-processors:
      - sample-processor
      - convert-int-processor

It looks like influxdb3 returns an OK string as a response on the health endpoint instead of a JSON message.
Influxdb3 is not supported by the library gNMIc uses (https://github.com/influxdata/influxdb-client-go).
There is a separate V3 client lib: https://github.com/InfluxCommunity/influxdb3-go

If you still want to run influxdb3 there might be corner cases where things fail.

Plans to add influxdb3 support?
