LoginRequest -> CredentialRequest

- We want to follow the <noun>Request convention.
- The actual operation does not login a user, but it does retrieve a
  credential with which they can login.

- This commit includes changes to all LoginRequest-related symbols and
  constants to try to update their names to follow the new
  CredentialRequest type.
