Description

The server's section in the metrics output looks like the following:

{
        "type": "server",                                                       
        "id": "kudu.tabletserver",                                              
        "attributes": {},                                                       
        "metrics": [ ... ]
}

It would be great to add the UUID of the server into the output along with "type", node/host name might be helpful as well.

The rationale is to be able to tell what tablet server the metrics were collected from once a JSON file with metrics is on hands, but there isn't information from which URL the metrics were collected. So, the UUID and the node name is to allow for easier identification of the collected metrics.
