**Description**:
As a tool developer I want to remove statements from a property so that my tool can remove incorrect data//As a gadget developer I want to remove statements from a property so that my tool can remove duplicated statements
DELETE /entities/property/{property_id}/statements/{statement_id}
DELETE /statements/{statement_id}
**Acceptance criteria:**
Responses:
- On the successful removal, API should respond with 200 and "Statement deleted" as a response body.
- 200 response should also contain Content-Language header with "en" as a value
- If the statement with the request ID does not exist, API would respond with 404 (replace with error table)
Notes:
- "Automated edit summary" related to the edit to be of form: /* wbsetclaim-update:1 (replace with the correct term from Action API)||1 */ [[Property:P123]]: VALUE_FORMATTED (exactly the same thing as for statement on items)
- client can provide additional edit metadata: mediawiki tags, edit summary text to append to the automated summary, and a bot edit flag, like in DELETE /entities/items/{item_id}/statements/{statement_id}
- Handle HTTP conditional request headers as in DELETE /entities/item/{item_id}/statements/{statement_id}
- Handle user authentication/authorization like in DELETE /entities/items/{item_id}/statements/{statement_id}
