chore: update k8s deploy config for local Minikube dev environment

- add eventrt-certs-secret.sh helper script for creating cert secret
  - update configmap: use K8s service DNS names for mongodb and jaeger
  - switch deploy_env to development and image to local eventrt:v1
  - add explicit command entrypoint to deployment manifest
  - update mongodb credentials to match local dev setup
