[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: 3persistentVolumes:
- mountPath: /opt/apache-doris/be/logname: be-logpersistentVolumeClaimSpec:
accessModes:
- ReadWriteOnceresources:
requests:
storage: 1Gi
- name: be-storagepersistentVolumeClaimSpec:
accessModes:
- ReadWriteOnceresources:
requests:
storage: 10Gi

operator constructs the following pvcs:
