SERVER-22541 Refactor RAII locking helpers.

Removes the class 'ScopedTransaction' and moves the responsibility of
abandoning the snapshot onto the GlobalLock class. Also renames the
AutoGetCollectionForRead class to AutoGetCollectionForReadCommand, and
adds a new AutoGetCollectionForRead class. Unlike
AutoGetCollectionForReadCommand, this new class will not update the
namespace on the CurrentOp object, nor will it add an entry to Top.
