Feature Request: Database level default connection configuration

[dantengsky]

Summary

Suggest introducing database level default connection options, something like this:

CREATE/ALTER DATABASE my_db
  OPTIONS (
      DEFAULT_STORAGE_CONNECTION = 'my_s3_connection',
      DEFAULT_STORAGE_PATH = 's3://mybucket/users/'
  );

Newly created tables of database my_db, without implicit connection options, should use the DEFAULT_STORAGE_CONNECTION/PATH specified at database level.
