[Feature] Check Influxdb integration

[kartone]

Is your feature request related to a problem? Please describe.
The configuration page for the integration with Influxdb is well done but sometimes the user, like me for example, makes a mistake when entering the required data (e.g. the url, port or the name of the organisation or bucket or the API token). It would be very useful, in my opinion, to have a Test button to check whether everything has been entered correctly.

Describe the solution you'd like
A simple Test button that verifies that all data is entered correctly, perhaps by doing a test data entry.
