Support Graphite's yMax (for both left and right y-axes)

[nhooey]

You could either grab the yMax parameter from the URL, or support your own min and max parameters specified in the TimeSeries widget type.

Yeah Graphite does not do anything with the yMax and yMin parameters when format=json is requested, so it's up to the view (in our case D3.js) to make that call. The min and max params on the TimeSeries seem like a good option! +1
