run_migrations_offline() async

Run migrations in 'offline' mode.

This configures the context with just a URL and not an Engine, though an Engine is acceptable here as well. By skipping the Engine creation we don't even need a DBAPI to be available.

Calls to context.execute() here emit the given string to the script output.
