Transition Redis to Serverless Instance

[bryan-robitaille]

Transition our Redis cluster from using a consistent reserved capacity (cache.t2.micro) to a serverless engine.

Pros:

• Reduced costs
• Ability to scale independently
• Leverage latest Redis engine (7.2)
  • Allows to leverage new JSON type instead of converting form configurations to strings.

Cons:

• Request application mitigation so that there is no downtime during the Production release.
