[FEATURE] A new unified api for all the entity list operations

### Describe the feature

We need a new unified api and name filter support for all the entity list operations.
The filter operation is above the tree UI, whatever filter catalog, schema or table name.
eg: A new unified api like: `api/v1/metadata ` get datas by `queryType` filter:

- list catalogs

```
curl 'https://xxxxx/api/v1/metadata' \
-H 'Accept: application/json, text/plain, */*' \
-H 'Accept-Language: zh-CN,zh;q=0.9' \
-H 'Cache-Control: no-cache' \
-H 'Connection: keep-alive' \
-H 'Content-Type: application/json' \
--data-raw '{"queryType":"CATALOGS"}'
```

- list schemas

curl 'https://xxxx/api/v1/metadata' \
-H 'Accept: application/json, text/plain, */*' \
-H 'Accept-Language: zh-CN,zh;q=0.9' \
-H 'Cache-Control: no-cache' \
-H 'Connection: keep-alive' \
-H 'Content-Type: application/json' \
-H 'Pragma: no-cache' \
--data-raw '{"queryType":"SCHEMAS","catalogIdentifier":{"catalogName":"catalog_hive"}}'

### Additional context

_No response_

Start by reviewing the proposed api/v1/metadata entry point and the example CATALOGS and SCHEMAS requests in the issue. Map the remaining entity list operations and name-filter requirements before defining the unified API contract. Done means the supported list operations and filters are consistently available through the new API.
