Influxdata cloud2 uses a different mechanism to enable tracing.
You need to pass a `influx-debug-id` header (the value is ignored) and if the response contains
`trace-sampled: true` then the response's `trace-id` header contains a valid trace ID that can be
used to jump to the trace in jaeger.
If the request has been sampled, we print the trace-id to stderr.
Since modern terminals allow to click on hyperlinks, we could avoid a copy&paste of the trace id
if the `influx` binary wrote a the link to the jeager trace.
However, we don't want to hardcode the URL of the internal jaeger endpoint in the binary.
I tried adding a wrapper script on my machine that would just capture the trace-id and render it, but it's
hard to do without messing with the ordering of the stderr and stdout lines.
Thus I preferred adding a secret env var that controls the formatting of the trace-id and can be used
by our devs to generate links to our internal jaeger instance.
```console
$ export INFLUX_CLI_TRACE_PRINT_PREFIX="Trace: https://jaeger.my.cloud/trace/"
$ influx query --trace-debug-id 123 -f query.flux
Trace: https://jaeger.my.cloud/trace/f39a69354a3acca6
Result: _result
Table: keys: [_measurement]
...
```
