Allow optional, temporary healthcheck failure.
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. Change-Id: I1759c78c74910a54c720f298d4d8e6fa57a4dab4
