legend_cols=int in bokeh

[rchurt]

I see here that users can put "...the legend elements in a column layout with legend_cols=True or (legend_cols=int in matplotlib)". Could you extend the legend_cols=int option to bokeh?

Thanks for the issue. This would have to be implemented in Bokeh first, see bokeh/bokeh#3880

@rchurt In element.py(L2059) legend_cols is only checked for True, any other value result in a vertical legend.

plot.legend.orientation = 'horizontal' if self.legend_cols else 'vertical'
