feat: Minimizing downtime of Ponder application on RailWay side

[RafaDSan]

Feature Request

Describe the Feature Request

As we are approaching the production environment we should prioritize the maximum uptime of the application as possible once the migration (issue 34) is completed.

Describe Preferred Solution

Not Working

• Configure the RailWay platform to make an instant reboot in the server once it has stopped
• Create redundancy with new instances so that the fetching process can be made for an instance that is working in case one is down

Zero Downtime Redeployments

• only route requests to a new instance once it is healthy and ready to handle requests.
