Business rules to determine if a Registration is eligible for Renewal

### User Stories

As the System
I want to designate a Registration as "eligible" for renewal if the Registration has an Active status and the expiry date for the Registration is less than 40 days in the future
So that the User can submit a renewal application for an active Registration that will soon expire in a timely manner.

As the System
I want to designate a Registration as "eligible" for renewal if the Registration has an Suspended status and the expiry date for the Registration is less than 40 days in the future
So that the User can submit a renewal application for an suspended Registration that will soon expire in a timely manner.

As the System
I want to designate a Registration as "eligible" for renewal if the Registration has an Expired status and the expiry date was less than 1,095 days (3 x 365 days) in the past
So that the User can submit a renewal application for an already expired Registration.

As the System
I want to prevent a Host from beginning a renewal process if the Registration they have selected is not eligible
So that the Host can be informed that the prior Registration can not be renewed and that a brand new Application must be submitted.

As the User
I want the ability to start a renewal process for a Registration that is eligible for renewal
So that I can continue my short-term hosting activities without disruption.
