[FlightRPC] Bearer Token refresh design with retry mechanism

- The generated bearer token by implementations of CallHeaderAuthenticator such as BearerTokenAuthenticator are bound to expire.
- The expired access token needs to be refreshed.
- The FlightClient needs to retry the API call on encountering FlightStatusCode.TOKEN_EXPIRED and refresh the expired token.

Refer to this [design document](https://docs.google.com/document/d/187DlGpIpOUPGhWvXVQEq0mXw_hdWjzzOuZp0p5qzBp0/edit?usp=sharing) for more details.

先從 FlightClient 和 CallHeaderAuthenticator 的實作開始，包括 BearerTokenAuthenticator，接著檢視連結的設計文件和 pull request #8780。完成標準是：過期 token 的回應會觸發 token 更新，且 FlightClient 會依規定重試 API 呼叫。
