DRILL-5319: Refactor "contexts" for unit testing
This PR is purely a refactoring: no functionality is added or changed.
The refactoring splits various context and related classes into a set
of new interfaces with needed for operator-level unit tests. The other,
Drillbit-related methods are left in the original interfaces. Most code
need not change.
The changes here allow operator-level unit tests to mock up the
exec-time methods so we can use them without firing up a Drillbit (or
using mocking libraries).
A later PR will provide the sub-operator test framework that uses this
refactoring.
Changes include:
* The OptionManager is split, with read-only methods moving to a new
OptionSet interface.
* The FragmentContext is split, with an exec-only FragmentExecContext
proving low-level methods.
* OperatorStats is split, with a new OperatorStatReceiver class
providing write-only support to operators.
* Several places that accepted an OperatorContext or FragmentContext,
but needed only an allocator, are changed to accept the allocator
directly.
