I can't get why you called it common and not config, and why we can't
have separate file for all this config options to parse it using
ConfigParser or similar tool.

I saw you added mysql relation to metadata.yml. It will be really cool
to have opportunity to connect it. Yay! But how and when are you going
create/migrate database for it? Also the question with config template
is still open.

Is it the last version? I'm not 100% sure it will work with changes in
relations. how do you plan to connect mysql relation here?
