Rename validation_workflow (which duplicates erp5_core's one.) to data_validation_workflow which ash one new state only 'Published'
Cleanup worklists.

This reverts commit ab6250a1.

Validates state's meaning is that it has passed a validation by content - either ebulk client side or Wendelin side. It's not meant to be part of publication context.

Make it possible to configure if default (open) security model is to be installed for Wendelin's Data Lake. Default is not install.

Add new states for Data Stream and Data Set so we can have a more complex security models (based on DMS' publication_workflow).
