The user configured weight of the real server for the
load-balancing algorithms. This is applicable only
in case of weighted Round Robin Predictor algorithms
(SlbPredictor values: 'roundRobin', 'leastConns').
A weight of zero indicates that no new connections will
be assigned to this real server.
Higher weight values indicate to the load-balancing algorithms
a higher availability of this real server to accept more work.
This object is applicable only for cesRserverType value 'host'.
