Add margins to histogram SVGs (#1085)

Browse Source 
* Add a left margin to histogram SVGs

Fixes https://github.com/chanzuckerberg/cellxgene/issues/1042

1. Added "margins" to the SVG as in https://bl.ocks.org/mbostock/3019563
2. Tailored the brushable area to be just where the data is and locked
   puppeteerUtils to use that in e2e testing.

* Dial in margins to avoid y-axis clipping
