Also added the Minio environment variables to the Kubernetes deployment.

Renamed from query-service-deployment to simply query-service. Added
resource limits and requests to both deployment and integration pod.
Added horizontal pod autoscaler to scale up query service based on cpu
usage.

Most of this code was taken straight from the schema service. No tests
were written because this is entirely dependent on external
dependencies.

Also updated Makefile and deployment file.

Together with Arjan.
