• the camunda-spin-dataformat-all should only contain all dataformats and their shaded dependencies
• camunda-spin-core should not be included

Central question:
Should dataformat-all contain core?

If yes, then we should remove core from the distributions that ship dataformat-all or else the core classes are present twice.

If no, then we should not shade core into the dataformat-all jar.

Same for connect.
