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).

This enables the default policy of Wendelin's data lake of "All can read but only authenticated can contribute."

Add two new bt5s and re-create the default configuration used for wendelin in both Scalability and Deployment tests.

By default enable automatic approval of credential requests if Wendelin's data lake bt5 is installed.
Add also proper warning accordingly.
