gRPC: disabled keepalive when sending control frames was blocked.

If sending request body was not completed (u->request_body_sent is not set),
the upstream keepalive module won't save such a connection.  However, it
is theoretically possible (though highly unlikely) that sending of some
control frames can be blocked after the request body was sent.  The
ctx->output_blocked flag introduced to disable keepalive in such cases.
