Properties are not documented well

[j-windsor]

Several properties on this module are not documented well. an example is backends: A huge object of dozens of properties, and none of them are documented. Luckily most are named well, but I don’t know where to start with properties like security_policy (probably a self link to something because it is a string but what type of resource?) and connection_draining_timeout_sec (obviously a time value but what does it control?).

Please improve documentation so users don't have to fish through the implementation to determine how to set properties.
