Not all things are managed by TouristMarketingCompany, some are managed
by generic organisations.
Those are now handled the same way as TouristMarketingCompany are
already handled.
That way those things can also be imported, as they now can import their
manager.
- Removed individual converters for TYPO3.
Conversion is now handled in a single converter.
- The new converter will import necessary dependencies upfront, e.g.
town or organisation.
- Move import state into extra class.

Use Symfony components to map incoming JSON onto objects.
Those provide a mapping. They can then be used to fetch the data in a
common way and insert it into the system.
- Handle languages within JsonDecode
(normalize incoming data based on language)
- Handle Single Value and List of Values within Entities. They will map
incoming Data to proper Objects. (We now generally transform during
serialization process if target is array but we got single entity)
- Add missing tests for existing data.
- Finish migration of all existing data, this includes next step
- Provide discriminator to ObjectNormalizer to auto detect target class
based on "type" property. (Done for now by own registry)
- Combine generated object with current structure for import -> generate
data array out of it.
- Resolve foreign references to existing entities,
(images, contentresponsible, etc.)
