Freature request: Load api-token automatically on provisioning of NodeRed flow. #140

It is not prossible to give the "InfluxDB out node" of this library a pre-shared api-token.

When InfluxDB boots it can load a token from an .env file but this is not prossible in the "InfluxDB out node" when setting up a server.

I have also tried to add an extra field to the JSON description of my flow to be able to set the api-token on load of this flow description, but this field is cleared every time the server connection is booted for the first time.

The node is storing and retrieving credentials like other nodes as described here.

I haven't tested yet, but environment variables should be able to be used in credentials properties as described in the user docs, so if you have a variable such as INFLUXDB_API_TOKEN if you put ${INFLUXDB_API_TOKEN} in that field, it should use it. This is similar to MQTT password as described here. Let me know if this works.

I had a similar problem. The environment variable solution works perfectly, even if the flows_cred.json is encrypted.
