emptyDir volume as a resource

[mathieu-benoit]

A volume res def needs to exist in the Humanitec Orchestrator:

apiVersion: entity.humanitec.io/v1b1
kind: Definition
metadata:
  id: volume-emptydir
entity:
  name: volume-emptydir
  type: volume
  driver_type: humanitec/template
  driver_inputs:
    values:
      templates:
        manifests:
          emptydir.yaml:
            location: volumes
            data: |
              name: ${context.res.guresid}-emptydir
              emptyDir:
                sizeLimit: 1024Mi
  criteria:
  - {}

Done in the different ref archs:

• emptydir_volume res def reference-architecture-gcp#32
• emptydir_volume res def reference-architecture-aws#32
• emptydir_volume res def reference-architecture-azure#22
• emptydir_volume res def reference-architecture-rhos#6
