Improve Prometheus stack

[gfrntz]

For the monitoring system, we need to prepare a set of dashboards, Prometheus configurations, or the monitor service, which can be installed either independently, specifying any, or depending on the set of installed applications.

For example, when installing the Nginx module, pre-configure monitoring of the Nginx controller and create a dashboard from which the status of the controller will be clear.
