Deprecate bound metadata
The :paramref:`_schema.MetaData.bind` argument as well as the overall
concept of "bound metadata" is deprecated in SQLAlchemy 1.4 and will be
removed in SQLAlchemy 2.0. The parameter as well as related functions now
emit a :class:`_exc.RemovedIn20Warning` when :ref:`deprecation_20_mode` is
in use.
Added new parameter :paramref:`_automap.AutomapBase.prepare.autoload_with`
which supersedes :paramref:`_automap.AutomapBase.prepare.reflect`
and :paramref:`_automap.AutomapBase.prepare.engine`.
Fixes: #4634
Fixes: #5142
