Add renderer setting UI component

[keiono]

There are many options for renderers. First, since we have several rendering options, it is better to provide user options to switch renderer type. Also, each renderer has its options for tweaking how the data is rendered in the view.

In the first iteration, the panel should provide the following options:

• Switching renderer

  • Cytoscape.js
  • Sigma.js w/WebGL renderer
  • Sigma.js w/ Canvas renderer

• Rendering options for each renderer

  • For Sigma: Label threshold, min/max node/label size, min/max zoom level
