F move entity

Summary

Introduction/Refactoring of move/copy constructors and assignment operators for several classes.

Focus

• Always mind the Rule of 5
• New move and copy constructors and assignment operators for DataType.
• New == and != operators for ProtoMessageWrapper and Entity (needed for testing).
• Simplified move constructor, copy/move assignment operators of Property.
• New move constructor, copy/move assignment operators for Entity.
• The new test cover all four things (move/copy constructors/assigment operators) for Entity, Property, and Parent.

Test Environment

Pipeline testing should be sufficient

Check List for the Author

Please, prepare your MR for a review. Be sure to write a summary and a focus and create gitlab comments for the reviewer. They should guide the reviewer through the changes, explain your changes and also point out open questions. For further good practices have a look at our review guidelines

• All automated tests pass
• Reference related Issues
• Up-to-date CHANGELOG.md
• Annotations in code (Gitlab comments)
  • Intent of new code
  • Problems with old code
  • Why this implementation?
