Compute and render service dependency graphs

See merge request !37

Graphs are shown in a modal fullscreen box, and they are not linked yet.

The app is now self-hosted instead of relying on the static-content
standalone server, so we can eventually add dynamic code for graph
serving.

The static content serving has improved, with more consistent cache
header management, as well as the capability of serving pre-compressed
content.

Additional code to implement the generation of dependency (flow)
graphs in dot format was added (not hooked to the HTTP server yet).
