Separate graph view component

[LuiggiTenorioK]

In a previous slide in the SURF GUI wireframes, they mentioned a feature to display the workflow graph somewhere in the system.

@mcastril had a great idea to share a common component to visualize the graph workflow view. This is a good opportunity to separate this component from the main project and publish it in npm. Then, this component can be utilized by anyone who wants to add a workflow visualizer to their own GUI using the data retrieved from the API.

Of course, this will be mainly designed to be a React Component. If this stays like this, we can also migrate to a more powerful network visualizer like React Flow. On the other hand, if in the future we want to also port this component to Angular or Vue, it will be better to stay using vis-network or, even better, migrate to D3.js which are native Javascript libraries.
