Create initial 2.0 engine implementation
Implemented the SQLAlchemy 2 :func:`.future.create_engine` function which
is used for forwards compatibility with SQLAlchemy 2. This engine
features always-transactional behavior with autobegin.
Allow execution options per statement execution. This includes
that the before_execute() and after_execute() events now accept
an additional dictionary with these options, empty if not
passed; a legacy event decorator is added for backwards compatibility
which now also emits a deprecation warning.
Add some basic tests for execution, transactions, and
the new result object. Build out on a new testing fixture
that swaps in the future engine completely to start with.
