[metrics] KUDU-3269: Add UUID and hostname of the server into the metrics output

This patch adds the UUID and the server hostname into the metrics
webpage of master and tablet server. These are added in the attributes
section of the metrics webpage. For example:

        "type": "server",
        "id": "kudu.master",
        "attributes": {
            "hostname": "MacBook-Pro.local",
            "uuid": "4b8015e347dd4efd92bb0d38e03434e6"
        },

> 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.
