Peter Portante 2d42b37303 Add the max_clients parameter to bound clients 
The new max_clients parameter allows one full control over the maximum
number of client requests that will be handled by a given worker for
any of the proxy, account, container or object servers.

Lowering the number of clients handled per worker, and raising the
number of workers can lessen the impact that a CPU intensive, or
blocking, request can have on other requests served by the same
worker.

If the maximum number of clients is set to one, then a given worker
will not perform another accept(2) call while processing, allowing
other workers a chance to process it.
