Copy the Metadata when Copying/Moving a Confluence Page

Currently, when copying a Confluence page with metadata all metadata sets/fields have to be configured again after moving.

Desired behavior: Metadata of the original Confluence page is also copied to the copy.

The followin should probably happen:

• Copy page:
  • In the same space: Correct metadata sets are applied and metadata values are copied
  • to different space
• Move page within the same space: leave everything as it is
• Move page to a different space: Print a message that metadata values will not be moved but rather removed. We could also display a notice for the end user about this

acceptance criteria:

• On copy inside a space
  • All metadata gets copied as well
• On copy/move to different space
  • All global metadata values get copied to the new destinationspace
  • the global metadatafields need to be in a global metadataset
• No metadata sets or fields will be created in the destination space
• space metadata values will be copied if
  • the destination field matches in type and configuration

thoughts about data integrity:

• we should not just copy the space metadtafields and sets to another space
  • because that would bypass the administration level for metadata in a space
• we should not just copy the data if the metadataf fields and sets in the other space have the same name/key
  • Data in the fields (especially the predefined fields like multiselect/singleselegt) can be completely different
  • it would potentially corrupt the copied data as well es the logical integrity of the destination data structure
