Must persist counter across restarts

[austurist]

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 Redis as data store
• counter will be stored as a name-value pair

Acceptance Criteria

Given I have incremented the value to 2
When service is restarted
Then the value of the counter is 2
