Prepare deployable application skeleton (app + db)

[pnpavlov]

Package all required components of the GLVD backend in a deployment manifest that can be applied to a Kubernetes environment. That includes but is not limited to:

• Helm charts for the GLVD API and for the database deployed in same namespace.
• The components of the chart need to decoupled in a way that enables managing them separately and exposing them within the environment over services. For now we can assume it's single namespace.

Not in scope:

• No High Availability or Disaster Recovery requirements to be covered during this early development stage.
