Vis utils (#277)

* checkpoint, adding overview plot done in plt instead of plotly

* checkpoint fixing the overview plots and adding the pairwise code

* updating comments to match line_length limits, adding mcmc chain plot

* checkpoint, integrating vis_utils into default behavior of abstract_azure_runner

* increasing fig size of overview

* changing size of the correlation_pairs plot

* tight bounding boxes to avoid text cutoff

* adding plotly back since it is still used by the azure visualizer for now
