Truncate all docs from collection

To truncate all docs from a collection, one need to put a DELETE request to end-point /collections/:collection/documents?truncate=true like below,

curl -H "X-TYPESENSE-API-KEY: ${TYPESENSE_API_KEY}" -X DELETE  "http://localhost:8108/collections/hnstories/documents?truncate=true"

Here, hnstories is the collection to truncate all docs.

And we get the response like below,

{"num_deleted":1000000}

Here num_deleted is the count of docs deleted.

In case of empty collection we get response accordingly,

{"num_deleted":0}
