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.

Fix bug 1129760
Without speed limit, DB auditor will likely consume high CPU% on
storage node. That will highly impact the cluster's performance.
This patch adds two options for account/container auditor:
- containers_per_second: Maximum containers audited per second
- accounts_per_second: Maximum accounts audited per second

A deployer may want to remove a Swift node from a load balancer for
maintenance or upgrade. This patch provides an optional mechanism for
this. The healthcheck filter config can specify "disable_path" which is
a filesystem path. If a file is present at that location, the
healthcheck middleware returns a 503 with a body of "DISABLED BY FILE".
So a deployer can configure "disable_path" and then touch that
filesystem path, wait for the proxy to be removed from the load balancer
pool, perform maintenance/upgrade, and then remove the "disable_path"
file.
Also cleaned up the conf file man pages a bit.
