Define k8s workload manifest for backend component

[andyatmiami]

🛑 Blocked by #323

Description

Presently, the only way to run the backend component is by invoking it locally on your machine. We must be able to run this component on kubernetes while also providing sufficient tooling to enable developers working on the component to easily deploy / undeploy the workload.

• See controller Makefile for deploy + undeploy examples

Acceptance Criteria

• Implementation is kustomize-compatible (but no overlays directory need necessarily be defined)
  • See controller folder structure for a (more complicated) example
  • manager subfolder might be a better specific/representative example
• Workload can be successfully deployed to k8s (enter READY state) using a deploy Makefile target
• Workload can be successfully undeployed from k8s using an undeploy Makefile target
• API endpoints function appropriately when workload running on cluster
