> Migrate OperatorFixture to use SystemOptionManager rather than mock

>                 Key: DRILL-5832
>                 URL: https://issues.apache.org/jira/browse/DRILL-5832
>             Project: Apache Drill
>          Issue Type: Improvement
>    Affects Versions: 1.12.0
>            Reporter: Paul Rogers
>            Assignee: Paul Rogers
>             Fix For: 1.12.0
>
>
> The {{OperatorFixture}} provides structure for testing individual operators 
> and other "sub-operator" bits of code. To do that, the framework provides 
> mock network-free and server-free versions of the fragment context and 
> operator context.
> As part of the mock, the {{OperatorFixture}} provides a mock version of the 
> system option manager that provides a simple test-only implementation of an 
> option set.
> With the recent major changes to the system option manager, this mock 
> implementation has drifted out of sync with the system option manager. Rather 
> than upgrading the mock implementation, this ticket asks to use the system 
> option manager directly -- but configured for no ZK or file persistence of 
> options.
> The key reason for this change is that the system option manager has 
> implemented a sophisticated way to handle option defaults; it is better to 
> leverage that than to provide a mock implementation.
