> HADOOP-10498 added proxyservers feature in ProxyUsers. It is beneficial to treat this as a separate feature since
> 1> The ProxyUsers is per proxyuser where as proxyservers is per cluster. The cardinality is different.
> 2> The ProxyUsers.authorize() and ProxyUsers.isproxyUser() are synchronized and hence share the same lock and impacts performance.
> Since these are two separate features, it will be an improvement to keep them separate. It also enables one to fine-tune each feature independently.
