Can an option for color_threshold be made available in Plotly dendrogram figure_factory?

[paulamool]

Plotly figure_factory create_dendrogram() clustering threshold is default and no option seems available to change this. This function is commonly used and very helpful to view large dendrogram clusters based on a colored distance threshold. enhancement

An attempt was made to update plotly/figure_factory/_dendrogram.py with a "color_threshold" (attached file) but it failed on CircleCI pull request "Added color_threshold to dendrogram #983", which is now closed.
dendrogram.zip

Any help would be greatly appreciated.
