What this PR does:

This pull request implements part of the backend for PD model and PD registrations. It did NOT yet add the database migrations, as there is no testing for anything yet.

How should this PR be tested?

Rspec and Cucumber after figuring out how everything connets.

• Are there edge cases to watch out for?
  Did not account for admin backend control yet, as in PD registrations logistics are not fully setup yet.

Are there any complications to deploying this?

No database migration or testing added yet.

Checklist:

• Has this been deployed to a staging environment or reviewed by a customer?
• Tag someone for code review (either a coach / team member)
• I have renamed the branch to match PivotTracker's suggested one (necessary for BlueJay) (e.g. michael/12345-add-new-feature Any branch name will do as long as the story ID is there. You can use git checkout -b [new-branch-name])
