[feature] Allow executing workflows on demand on Kubernetes by running server process only when necessary

[ivicac]

As a User

I want to be able to run workflows on demand

So that I can execute workflows on demand on Kubernetes by running the server process via the Kubernetes scheduler

Technical Details

• The Kubernetes scheduler should send the signal for running the server process; it reads and executes workflows and shuts down
• The server process is preconfigured to be run in-memory, no state is written to database

Acceptance Criteria TODO
