Document plotly.py orca integration

[jonmmease]

plotly.py version 3.2.0 is going to feature full orca integration for exporting figures as static images.

I've created two notebooks that cover the new functionality at https://github.com/jonmmease/plotly_orca_notebooks.

StaticImageGeneration.ipynb covers the new high-levelto_image and write_image functions in the new plotly.io package.

OrcaManagement.ipynb covers the lower-level interface to the orca server process.

I'd like to get these into the main docs soon.

I think putting these new docs either together or separately on the front page in Plotly fundamentals would be best.

We would also make a new section for the new plotly.io modules Jon is working on.

WDYT? @jonmmease @cldougl

Sorry, I forgot to reference this issue from my PR #1058

Right now I put these as two new sections in fundamentals. I think I made them positions 2 and 3 so that they will show up on the front page.

When the plotly.io module is fleshed out and documented I expect we may have around 10 tutorial pages for that. So it would probably make sense to eventually create a new section for plotly.io, and then move these two image-export/orca notebooks to the new section at that point.

@jonmmease is resolved now that the docs have been deployed with #1058 or are there additional tasks that should be competed?

[jonmmease]

Nope. This is done. Thanks for following up!
