title: Creating "zero state" migration for existing db with sqlalchemy/alembic and "faking" zero migration for that existing db
body: <p>I want to add alembic to an existing ,sqlalchemy using, project, with a working production db. I fail to find what's the standard way to do a "zero" migration == the migration setting up the db as it is now (For new developers setting up their environment) </p>
  
  <p>Currently I've added import the declarative base class and all the models using it to the env.py , but first time <code>alembic -c alembic.dev.ini revision  --autogenerate</code> does create the existing tables. </p>
  
  <p>And I need to "fake" the migration on existing installations - using code. For django ORM I know how to make this work, but I fail to find what's the right way to do this with sqlalchemy/alembic</p>
