Patch implementing the desired funcionality

This is a patch we're using in production from some years now.

This adds a new configuration parameter to load balancer workers, named
lb_retries.

There can be set the number of retries when a request to upstream fails. Right
now the behaviour we observe is that in case of failure the LB retries to all
workers at least once. When all backends are busy this adds even more load in
our experience.

Please consider merging, and ask for any additional info needed.


Thanks
