[ResponseOps][Actions] Research how we can persist information related to resources in external services

[cnasikas]

Rules, through actions, can interact with external services like ServiceNow or Jira. Incidents or issues can be opened in this service when an alert is triggered. Some services offer mechanisms where you can refer to the resource created in the external service and update or delete it. This is not possible in some cases, like Jira or OpsGenie. It became apparent that to support any external service, we would need to persist in information about the resource created in the external service to be able to interact with the resource. We should gather requirements, research, and propose solutions that will aid us achieve our goal.

DoD

• Gather requirements and user scenarios
• Research and propose a solution
