User Cluster Backup Configuration for Minio Backend via KKP UI

[toschneck]

Description of the feature you would like to add / User story

As a KKP project admin
I would like to configure as backup target an minio endpoint
in order to use my existing seed minio or self-hosted minio

Solution details

Currently the UI doesn't have an option to set all parameters of the AWS Backupstorage Class of Velero.

E.g. for minio it's required to set the value s3ForcePathStyle: "true"

To be generic, it would be good to have an additional yaml block field to add additional parameters to the config for the Backup Storage Location (for AWS) Object

Alternative approaches

Currently a config via the CRDS is possible, but not documented (see kubermatic/docs#1707)

apiVersion: kubermatic.k8c.io/v1
kind: ClusterBackupStorageLocation
metadata:
  labels:
    csbl-display-name: seed-minio
    project-id: nczgr7n44g
  name: seed-minio-nczgr7n44g
  namespace: kubermatic
spec:
  backupSyncPeriod: 1m0s
  config:
    region: minio
    ####  NOTE: URL must be accisble from the user cluster network scope
    s3Url: https://minio.demo.kubermatic.io 
    # Whether to use path-style addressing instead of virtual hosted bucket addressing. Set to "true"
    # if using a local storage service like MinIO.
    #
    # Optional (defaults to "false").
    s3ForcePathStyle: "true"
    # If specified, use this instead of "s3Url" when generating download URLs (e.g., for logs). This
    # field is primarily for local storage services like MinIO.
    #
  credential:
    key: cloud-credentials
    name: credential-seed-minio-nczgr7n44g-h6qkj
  objectStorage:
    bucket: user-cluster-backup
  provider: aws
