[Bug]: [HELM] Deployment name too long

### What is your environment, configuration, and command?

The deployment name is way too long and confusing when deploying through helm, we should make it shorter.

e.g.

```
spark-history-server-mcp-spark-history-mcp   1/1     1            1           5m20s
```
