[Improvement][Helm Chart] Support HDFS HA

### Search before asking

- [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement.

### Description

The helm chart support HDFS HA.

### Use case

Now, the config option has "resource.hdfs.fs.defaultFS".
And the comment say "if resource.storage.type=HDFS and namenode HA is enabled, you need to copy core-site.xml and hdfs-site.xml to conf dir", but the template not use the "conf" dir or "config" dir.
The pod only mount common.properties.

I want some ways to support HDFS enabled HA. Maybe some option for the xml files in common.properties, or some mount.

And, i m using HDFS deployed by stackable hdfs operator, the core-site.xml and hdfs-site.xml are ConfigMaps. Maybe some way can use this.

Start by inspecting the Helm chart template and pod volume mounts around common.properties, especially the conf or config directories. Review how core-site.xml and hdfs-site.xml are expected to be supplied, including ConfigMaps from the Stackable HDFS operator. Done means the chart provides a documented way to configure HDFS HA and makes both XML files available to the pod.
