scraping: delay creating buffer, to save memory (#12953)
We don't need the buffer to read the response until the scrape http call
returns; creating it earlier makes the buffer pool larger.

I split `scrape()` into `scrape()` which returns with the http response,
and `readResponse()` which decompresses and copies the data into the
supplied buffer. This design was chosen to minimize impact on the logic.
