readme should warn about Influx API version

[zbrozek]

The v2 API uses generated tokens rather than passwords, and there's some effort to go through to generate a v1-compatible authentication token.

https://docs.influxdata.com/influxdb/v2.0/reference/cli/influx/v1/auth/create/

I don't know if this is sufficient - my setup is still not working - but creating a v1 auth token allowed me to move on to a different form of failure.

I ended up unable to get things working with the v1 API, so I just edited the code and now it's using the v2 API and is working properly. It's probably worth moving the whole project to v2.
