Closes #630.

In a multi-node cluster the bundled dashboard's per-GPU legends collide: every node shows GPU 0, GPU 1, ... with no way to tell them apart (see the screenshot in the issue). This prepends the Hostname label so each series reads <hostname> GPU <n>.

Only the 6 per-GPU panels are changed; the cluster-wide avg/sum panels (empty legend) are left as-is.

Format is open to preference -- happy to use {{instance}} instead of {{Hostname}}, or a different separator, if the maintainers prefer.

…cross nodes
