There is a number of annoyances and pending improvements when working with the Salt Formula for provisioning Prometheus Exporters in Uyuni:

• Fix issue with cleanup in case the monitoring entitlement is removed.
• Single system vs. group assignment: make it visible in the UI in case there is a group level assignment.
• Automatically create a corresponding firewall configuration when provisioning Prometheus exporters.
• Create a better identifier for Formulas rather than just matching the Formula name in the code.
• Refactor the validation code: extract methods to a separate validator class and keep FormulaManager clean from it.

Progress during Hackweek 19:

Only the first item from the above list could be finished, a fix has been merged to Uyuni master with https://github.com/uyuni-project/uyuni/pull/1643.
