[TECH DEBT] Revisit why we are using Features in Controlled Access Terms Defaults

[rosiel]

Controlled Access Terms and its's Defaults were designed to be usable with any Drupal, even one that does not use Islandora. I believe they work OK in that capacity.

Is a Feature still the desired way to ship Controlled Access Terms Defaults? Features imply some level of receiving updates.

Now that Islandora Defaults is a Starter Site we thought it would be a good opportunity to revisit why we made some modules as Drupal Features.
