Add context map visualisation

[mrchtr]

• Add visualisation itself. If the graph contains elements jqa-ddd-plugin the bounded contexts could be visualized by the context map visualisation
• Add d3-graph-react for graph visualisation with the use of d3
• Add docker container and a dump file to provide a way for quick testing
