As a developer, I want to be able to create a new Wikidata item in its entirety
`POST rest.php/wikibase/v0/entities/properties`
```
{
"property": {
"data_type":
"labels": {},
"descriptions": {},
"aliases": {},
"statements": {}
},
"comment": ... (optional)
"tags": [ ... ] (optional)
"bot": false (optional)
}
```
**Acceptance criteria**
- 201 response code on success and location header in the successful creation response
- Ignore HTTP conditional request headers
- Ignore id and type fields and don't consider them unexpected
- ETag, last-modified and location (URI of the newly created item) as response headers.
- Handle user authentication/authorization like in `POST /entities/items/{item_id}` **[double check because property creators have special rights]**
- Client can provide additional edit metadata: mediawiki tags, edit summary text to append to the automated summary, and a bot edit flag, like in POST /entities/items/{item_id}
