Add import/export/duplicate for datasources

[bijwaard]

Dear grafana developers,

What would you like to be added:
It would be great to be able to import and export datasources by file via the web frontend. Duplicating a datasource (e.g. similar to what can be done with metric queries) would also save configuration time.

Why is this needed:
I have about 20 datasources from embedded sensor devices (JSON and influxdb) per grafana server (on embedded device) and would like to easily re-populate them on the grafana server of a sensor clusters that runs elsewhere.

I found scripts to import/export datasources, but this requires shell access to obtain&re-deploy the datasources and transport them somehow between unconnected private networks.

Kind regards,
Dennis

This issue still exists, by now there are also 100+ datasources on my server, including influxdb from local and remote sensors, live websocket and JSON from sensors.

Easy management and duplication of datasource entries would be very helpful. Most entries are quite similar except for URL and credentials.
