[improve](dcr) support pvc template and be multi-data disk

[catpineapple]

What problem does this PR solve?

Improved the flexibility of DCR PVC configuration, configured the storage path according to fe.conf/be.conf, and implemented the configuration of be multi-data disk from ‘storage_root_path’.

storage_root_path=${DORIS_HOME}/aaa;${DORIS_HOME}/sss;${DORIS_HOME}/ddd

The above configuration allows Doris be to mount three data disks as data storage media according to the following configuration

  beSpec:
    replicas: 3
    persistentVolumes:
    - mountPath: /opt/apache-doris/be/log
      name: be-log
      persistentVolumeClaimSpec:
        accessModes:
        - ReadWriteOnce
        resources:
          requests:
            storage: 1Gi
    - name: be-storage
      persistentVolumeClaimSpec:
        accessModes:
        - ReadWriteOnce
        resources:
          requests:
            storage: 10Gi
