InfluxDB 2.X (Auth) Support

[mweber89]

In InfluxDB 2.x, passing the token or username/password directly within the URL is not supported. The recommended method is to include the authentication information in the request headers. This helps ensure secure transmission of sensitive information.
I can't find in the docs, how to configure request headers, hence the request to have a closer look into the InfluxDB 2.x requirements.

According to influxdb doc, Basic Authentication is still supported in InfluxDB 2.x by using the InfluxDB 1.x compatibility API:
https://docs.influxdata.com/influxdb/v2.7/reference/api/influxdb-1x/

Note that when you have username and password or token in the influxdb url as explained in the javamelody doc, javamelody will in fact send a http request header like Authorization: Basic INFLUX_USERNAME:INFLUX_PASSWORD_OR_TOKEN as explained in influxdb doc:
https://docs.influxdata.com/influxdb/v2.7/reference/api/influxdb-1x/#basic-authentication
So yes, a http request header is already used by javamelody and not query string parameters.

The header is set here, if you search it:

And I have added support to set an influxdb-api-token parameter like the influxdb-url parameter: cd34d03 and ea73a31
