SUMMARY

s3 based secondary storage is not removed cleanly

**Steps to reproduce the behaviour**

1. Create a s3 based secondary storage

2. Enable the NFS secondary staging storage

3. Cross check the database

```
select * from image_store
*************************** 2. row ***************************
id: 2
name: s3
image_provider_name: S3
protocol: https
url: NULL
data_center_id: NULL
scope: REGION
role: Image
uuid: 5aea84cb-da61-4eba-b4d6-a2cc6683bd53
parent: NULL
created: 2024-10-14 11:27:53
removed:
total_size: NULL
used_bytes: NULL
readonly: 0
*************************** 3. row ***************************
id: 3
name: nfs://10.0.32.4/acs/secondary/ref-trl-7483-k-Mol8-kiran-chavala/ref-trl-7483-k-Mol8-kiran-chavala-sec1
image_provider_name: NFS
protocol: nfs
url: nfs://10.0.32.4/acs/secondary/ref-trl-7483-k-Mol8-kiran-chavala/ref-trl-7483-k-Mol8-kiran-chavala-sec1
data_center_id: 1
scope: ZONE
role: ImageCache
uuid: 18cc19bd-e840-48b4-ae6a-0e99f2ca563a
parent: NULL
created: 2024-10-14 11:27:53
removed: NULL
total_size: NULL
used_bytes: NULL
readonly: 0

```

4. Remove the s3 secondary storage

Only the role image entry is marked removed , the role: ImageCache entry is not marked as removed

```

removed: NULL
total_size: NULL
used_bytes: NULL
readonly: 0
```



Actual Behaviour

The role role: ImageCache entry is not marked as removed, which is causing issues during later when a new secondary storage is added and a migration activity is performed

Expected Behaviour

The role role: ImageCache entry should also be marked as removed when s3 based secondary storage is removed

从 S3 存储的辅助存储删除工作流开始，跟踪启用 NFS 暂存时相关 image_store 条目的处理方式。重现列出的步骤，然后验证删除后 Image 行和 ImageCache 行是否都被标记为已删除，并确认后续迁移和存储创建不再遇到该过时条目。
