> Remove observers from configuration

>                 Key: ACCUMULO-4822
>                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4822
>             Project: Accumulo
>          Issue Type: Improvement
>            Reporter: Keith Turner
>            Priority: Major
>             Fix For: 2.0.0
> As part of the work done for ACCUMULO-4779 the method getUpdateCount was 
> added to AccumuloConfiguration.  Subclasses of AccumuloConfiguration increase 
> a counter each time it changes and this counter is available via 
> getUpdateCount.  Anything that is derived from configuration can be cached 
> and this counter can be used to know when it needs to be derived again.
> Some AccumuloConfigurations are also observable.  I think this observer 
> pattern could be dropped in favor of using this counter.  I think this change 
> would simplify the code.
