DOC: configuration: Clarify wait-for-body doc for the response side

The documentation was too request-oriented and did not mention the 504
"Gateway Timeout" error returned to the client when the timeout occurs while
waiting for a response body. It is now side-neutral and explicitly mentions
the 408 and the 504 errors returned on timeout, depending on the side.

   This will delay the processing of the request or response until one of the
   following conditions occurs:
-  - The full request body is received, in which case processing proceeds
+  - The full message body is received, in which case processing proceeds
     normally.
   - <bytes> bytes have been received, when the "at-least" argument is given and
     <bytes> is non-zero, in which case processing proceeds normally.
-  - The request buffer is full, in which case processing proceeds normally. The
-    size of this buffer is determined by the "tune.bufsize" option.
-  - The request has been waiting for more than <time> milliseconds. In this

     not yet been received.
