Add request data visualisation

[cebilon123]

Context:

Currently, there is no way to visualize what requests are coming through our WAF. At the very beginning, we need a frontend that simply visualizes the incoming requests.

It could be done as a list of incoming requests and some kind of graph.

TODO

• add a request visualization (currently we don't have any metrics gathering code, so this needs to be done as well)

AC

• we have an incoming request visualization
• there is high test coverage

Info

We could create our custom frontend i.e. in React, or we can try using Grafana, share some ideas here, and let's discuss 😄

For now we are going with the grafana.
