Drupal 8 || 9 compatibility implementation

Problem/Motivation

The new drupal8||9 core version already has all requirements which were used to implement the data model for this module for drupal7
We have received a request for implementation of compatibility with drupal 8 in 2017 from General Motors.
Nowadays we have claimed registration of a trademark for this module as a product, along with service delivery provided by Alef Invest

Proposed resolution

Remaining tasks

todo: Create a Backlog

User interface changes

API changes

Data model changes
