`closed = true` should happen after the call to `super.close()` since base
class close can throw exception.
> Refactor and simplify the fragment, operator contexts for testing

> Key: DRILL-5842
> URL: https://issues.apache.org/jira/browse/DRILL-5842
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.12.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Fix For: 1.12.0
>
>
> Drill's execution engine has a "fragment context" that provides state for a
> fragment as a whole, and an "operator context" which provides state for a
> single operator. Historically, these have both been concrete classes that
> make generous references to the Drillbit context, and hence need a full Drill
> server in order to operate.
> Drill has historically made extensive use of system-level testing: build the
> entire server and fire queries at it to test each component. Over time, we
> are augmenting that approach with unit tests: the ability to test each
> operator (or parts of an operator) in isolation.
> Since each operator requires access to both the operator and fragment
> context, the fact that the contexts depend on the overall server creates a
> large barrier to unit testing. An earlier checkin started down the path of
> defining the contexts as interfaces that can have different run-time and
> test-time implementations to enable testing.
> This ticket asks to refactor those interfaces: simplifying the operator
> context and introducing an interface for the fragment context. New code will
> use these new interfaces, while older code continues to use the concrete
> implementations. Over time, as operators are enhanced, they can be modified
> to allow unit-level testing.
