Contracts now support custom field values — readable and writable through
the existing Contracts endpoints — and Custom Field definitions can be
scoped to Contracts.

Added

Contracts

• Added a custom_fields field to Contracts, returning the company's
  Contracts-scoped custom field values for each contract. custom_fields
  can be filtered like any other field.
• Custom field values can now be set on Contracts through the existing
  create and update endpoints, using the custom_fields field in the
  request body.

Custom Fields

• Custom Field definitions can now be scoped to Contracts. The
  entity_type field accepts a new contracts value, in addition to the
  existing applications and payments values.
