provide option to draw grid above traces

[cldougl]

Add attribute to affect the z-order of the x and y axes gridlines such that the traces added to my figure do not obscure the gridlines, by default the traces are always drawn on top of the grid lines.

Feels like there are at least three layers we might want the grid to be in:

• behind all data (where it is today)
• in front of all data
• above heatmaps and contour maps, but below scatter. Actually maybe also above bars too, so you could do the "minimal ink" gridlines matching the background and only visible on the bars but still put scatter points on top without the gridlines chopping them up.

@alexcjohnson is there a way to get "minimal ink" styling somehow nowadays?

Any update on this? Looking for the same thing

Any workaround that does not involve creating a bunch of shapes?

This is important, for example, in order to be able to see deviation from an axis on a scatter plot with a large about of data (which obscures grid lines). You should also be able to set just the zeroline above the plot.
