DRILL-3921: Initialize the underlying record reader lazily in HiveRecordReader

This closes #197

+ OperatorContextImpl has a lazily initialized executor service that is

 a decorator around the worker pool. This service is used through

 #runCallableAs to run a callable task as the given proxy user.

+ Unit tests use partition student table with chained impersonation to

 exercise running multiple delegate callables (creates multiple readers,

 a reader per partition).

+ Remove unused WorkManager#shutdownAndAwaitTermination method
