Fixes to allow nesting of subdags

decorators

Every decorator should have access to this, just in case, so we don't have to worry about passing it through. This changes the resolve_config function in function_modifiers.base to pass it through globally. Note that this also removes the default setting of this in the @resolve(...) decorator as it is no longer necessary.

Furthermore, this cleans up some issues in which the optional configs provided by a decorator was a list instead of a dictionary.
