[EAK-616] Proposal: common package to share reusable utilities and features

[ala-n]

Problem

Projects

• https://github.com/exadel-inc/etoolbox-authoring-kit
• https://github.com/exadel-inc/etoolbox-rollout-manager
• https://github.com/exadel-inc/etoolbox-backpack
• https://github.com/exadel-inc/etoolbox-link-inspector
  have a lot of common code and functionality to share:

1. UI utilities (misc, e.g. debounce; UI creation, e.g. create dialog, create progress UI)
2. Depends On - apart from the simplification of behavioral form, DependsOn shares utilities to work with Granite/Coral fields
3. Sub-project Configurator - for configuration :) (similar solution partially presented in link inspector, there is a need in other projects)
   3.1. It seems like it will be good to distribute DependsOn with Back-end annotations and renderer together with Configurator

Proposal:

Investigate the possibility of creating a common package for the described functionality

Open Questions

• Version management from the EAM perspective
• Architecture of package dependencies in those cases
• TBD
