Introduced AuthenticationMode for Customer

We introduced the AuthenticationMode that controls whether the password field is required for a Customer in public beta. The Password authentication mode is the default mode for backwards compatibility that requires to set a password for the Customer. For use cases where Customers are authenticated externally, you can now set the authenticationMode to ExternalAuth to create Customers without a password.

Changes:

• [API] Added authenticationMode field to Customer and CustomerDraft.
• [API] Changed password field to be optional on CustomerDraft when authenticationMode is set to ExternalAuth.
• [API] Removed password field from Customer when authenticationMode is set to ExternalAuth.
• [API] Added Set AuthenticationMode update action.
• [GraphQL API] Added the following types to the GraphQL schema: AuthenticationMode, SetCustomerAuthenticationMode.
• [GraphQL API] Changed the Customer type:
  • Customer.password field type changed from String! to String
  • Added the authenticationMode field to the Customer type.
• [GraphQL API] Changed the CustomerSignUpDraft type:
  • CustomerSignUpDraft.password input field type changed from String! to String
  • Input field authenticationMode was added to CustomerSignUpDraft type
• [GraphQL API] Changed the CustomerUpdateAction type:
  • Input field setAuthenticationMode was added to CustomerUpdateAction type
• [GraphQL API] Changed the CustomerSignMeUpDraft type:
  • CustomerSignMeUpDraft.password input field type changed from String! to String
