change the default value for prefer_database_credentials to true ...

... and deprecate this setting.

In the future we'll remove prefer_database_credentials and
credentials_path and we will not allow the credentials to be saved on
the filesystem

The flags can be combined, for example 6 means public keys and keyboard interactive
