I tried a prototype locally, the e2e data flow will looks like:
```
EXPLAIN ANALYZE <query>
│
▼ planner.rs
LogicalPlan::Analyze detected
│ strip wrapper, extract inner plan + verbose flag
▼
DistributedQueryExec::with_action(..., ExplainAnalyze { verbose })
│ schema = (plan_type TEXT, plan TEXT)
▼ distributed_query.rs
execute_explain_analyze()
├── submit_job(inner_plan) → job_id
├── poll until SUCCESS
├── scheduler.get_job_metrics(job_id) → Vec<StageMetrics>
│
▼
each stage: "Stage N:\n <plan_text>\n"
│
▼
RecordBatch { plan_type: ["distributed plan"], plan: [<formatted text>] }
```
