[LarryWang142]

Is your feature request related to a problem? Please describe.

stuff for integrate s3 storage client is not planed in the next release of DMP, so we need RadonDB MySQL Operator provide some necessary informations to implement one-step restore function(create a new cluster from a backup).

Existing information:

spec:
  clustname: radondb-npbw4y
  historyLimit: 3
  hostname: radondb-npbw4y-mysql-1
  image: radondb/mysql-sidecar:v2.1.2
status:
  completed: true
  conditions:
  - lastTransitionTime: "2022-04-14T07:29:08Z"
    message: ""
    reason: ""
    status: "True"
    type: Complete

restoreFrom is missing in Backup CR

spec:
  backupSecretName: $S3_SECRET_NAME
  restoreFrom: "backup_20224147294"

Describe the solution you'd like
