ProxyPartitionKey does not implement hashCode or equals and is used in a hash map.

We are using 1.9.31 and seeing many many debug statements every minute, e.g.

DEBUG default    c.n.h.c.p.n.c.p.DefaultChannelPool - Closed 0 connections out of 0 in 0ms
2016-01-11_18:02:53.12600 2016-01-11 18:02:53.125 DEBUG default    c.n.h.c.p.n.c.p.DefaultChannelPool - Entry count for : ProxyPartitionKey(proxyUrl=https://proxy:3128, targetHostBaseUrl=https://test:443 : 0
2016-01-11_18:02:53.12608 2016-01-11 18:02:53.125 DEBUG default    c.n.h.c.p.n.c.p.DefaultChannelPool - Entry count for : ProxyPartitionKey(proxyUrl=https://proxy:3128, targetHostBaseUrl=https://test:443 : 0
2016-01-11_18:02:53.12610 2016-01-11 18:02:53.126 DEBUG default    c.n.h.c.p.n.c.p.DefaultChannelPool - Entry count for : ProxyPartitionKey(proxyUrl=https://proxy:3128, targetHostBaseUrl=https://test:443 : 0

This grows every time there is a successful connection. I believe this is because the key being used does not implement either hashCode() or equals()

Fix, thanks for reporting!
