Title: Use a method instead of a constant to return the schema of a query.

I'm opening a pull request to start discussing this change just because it was easy enough to change the related code, but I'm still not sure if I'm missing some reasoning behind the current code.

I was wondering why we use a constant instead of an instance method to return the schema of a query, I don't think we even need to have it public or defined in the underlying interface since it is purely an implementation detail of the `Congow/Orient/Query/Command` abstract class.
