Upstream hash: limited number of tries in consistent case. While this may result in non-ideal distribution of requests if nginx won't be able to select a server in a reasonable number of attempts, this still looks better than severe performance degradation observed if there is no limit and there are many points configured (ticket #1030). This is also in line with what we do for other hash balancing methods.
