> 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.
