Upgrade Notices

This release of minio migrates the chart to the passthrough pattern.

Values overrides are now nested under the upstream key. For example:

addons:
  minio:
    values:
      tenant:
        pools:
        - name: pool-0
          servers: 3
          volumesPerServer: 4

becomes:

addons:
  minio:
    values:
      upstream:
        tenant:
          pools:
          - name: pool-0
            servers: 3
            volumesPerServer: 4

Labels have also slightly changed:

Old:

labels:
  app: minio
  app.kubernetes.io/name: minio

New:

labels:
  app.kubernetes.io/name: minio-instance
