Must persist counter across restarts

[SA-HD]

As a Service Provider
I need the service to persist the last known count
So that users don't lose track of their counts after the service is restarted

Details and Assumptions

• We will use a Redis database

• Counter will be stored as name value pair

  Acceptance Criteria

  Given I have incremented the counter to 2
  When I restart the service
  Then the counter should still return 2
