Add support for Multiple metrics "{metric1,metric2}" about grafana

Thanks for opening this ticket. This is something the lexer / parser needs to handle. Just skipped this for the initial release. Will be a priority moving forward.

In that image, the show/hide button for the target is a yellow triangle, even though the target is valid. Is there any way to fix the show/hide button to be available regardless of the target? I have a hand-written target like this: scale(divideSeries(system1.memory.used,system1.memory.total),100) and I can't unhide it without messing with the dashboard json in elasticsearch.

@benpillet The parser warning icon in now shown to the right, so the hide/show can always be used. (a9ac112)
