monitoring: T4411: Migrate influxdb options to influxdb node

As we have specific configuration for each plugin:
set service monitoring telegraf xxx
 - azure-data-explorer
 - prometheus-client
 - splunk

We should to move configuration that related to influxdb under
influxdb node

Replace:
set service monitoring telegraf
 - authentication xxx
 - bucket xxx
 - port xxx
 - url

To:
set service monitoring telegraf influxdb xxx
