Notification for changes to NetDebitCap or Position adjustments

[elnyry-sam-k]

Goal:
As a Hub Operator
I would like to provide notifications for changes to NetDebitCap or Position adjustments
so that participating FSPs and the Hub Operator can be informed

Tasks:

• Design notification strategy for notifications for changes in NetDebitCap or Position adjustment[ @bothadeon , @vgenev ]

• Trigger a notification for changes in NetDebitCap (change from the API) when NetDebitCap change is spotted on transfer [ @bothadeon , @vgenev ]

• Trigger a notification for changes in Position of an FSP - only for Position reset/adjustments as part of the Settlement process (not every position change as part of the usual transfer) - settlement API is synchronous atm

• Unit tests (Covered in Automated testing - unit, etc tests for central-event-processor component #558)

• Release feature

  • Deployment on dev environment [ @elnyry , @vgenev ]
    • Deployment (Circle CI & Github Repo)
  • Dockerize the repo .[ @bothadeon , @vgenev ]
  • Implement the health checks endpoint for Kubernetis .[ @bothadeon , @vgenev ]
  • Develop Helm chart for deployment.[ @bothadeon , @vgenev ]
  • Kubernetes installation and deployment test.[ @bothadeon , @vgenev ]
  • AWS Deployment.[ @bothadeon , @vgenev ]

Acceptance Criteria:

• A notification (or notifications) is (/are) sent to an FSP when a change is made to the Net Debit Cap or Position adjustment is done
• A notification (or notifications) is (/are) sent to an FSP when a Position adjustment is done
• Both FSPs and the Hub Operator receive these alerts/notifications
