InfluxDB registry does not support InfluxDB cloud / v2

[sbaier1]

The influxdb registry does not currently support parameterization for InfluxDB cloud.
This means that metrics cannot be written to an InfluxDB cloud bucket.
The main difference are authN/authZ tokens instead of basic auth as well as difference in the
HTTP parameters themselves (in a nutshell: db -> bucket and there is a new mandatory parameter org)
This will require changes to the configuration format.

An implementation of such a cloud sender we have done: https://github.com/hivemq/hivemq-influxdb-extension/blob/master/src/main/java/com/hivemq/extensions/InfluxDbCloudSender.java
