Benchmark in histogram

Explicit value that can be set in the histogram panel that shows up as a line in the histogram view. The color of the line can also be set from the panel.

Below a benchmark of 10,000 was set with a color of red.

I'd love to see this! I think we'd use it for more than half our histogram panels.

+1 cool idea. It would be very useful.

Loosely related to #1304 and likely some other color related requests. To be discussed...

There's now a work around for this. You can add a scripted field to Kibana 4 that always returns a static number, then add a metric agg that just displays the average (or min or max, it doesn't matter, they're all the same)

This looks like a dup of #5037
