 - `BearerTokenCredentialPolicy` and `AsyncBearerTokenCredentialPolicy` now first check if a credential has the `get_token_info` method defined. If so, the `get_token_info` method is used to acquire a token. Otherwise, the `get_token` method is used. #36565
   - These policies now also check the `refresh_on` attribute when determining if a new token request should be made.
