Delete asset group

Upstream cannot delete a non-empty asset group, so the gateway deletes the assets one by one first, then the group. The request may therefore take a while; if the group holds too many assets it returns 409 and you need to clear it yourself first.

curl -X POST "https://jiniu.ai/api/material?Action=DeleteAssetGroup" \  -H "Content-Type: application/json" \  -d '{    "Id": "group-xxxx"  }'
