Add a Drupal Core Version field in the documentation content type

Follow-up to #2802095: Need new guide for Managing site performance and scalability under Drupal 8 documentation


Drupal 8 core cdn works with 8.1.4+…
Right now we have added it on the project page.

Proposed resolution

Add a new field(Entity Reference) in the content type that would pull the branches/tags from the project version schema(not sure which schema) and it will allow users to select with which versions the of drupal core, the module is compatible with.

Remaining tasks

User interface changes

API changes

Data model changes
