[I] [Java][FlightSQL] In authentication, how does flight server get the IP/Hostname of ADBC client [arrow]

   ### Describe the usage question you have. Please include as many useful 
details as  possible.
   
   
   Now I implement `CallHeaderAuthenticator` in Java, and Override `AuthResult 
authenticate(CallHeaders incomingHeaders)`.
   ```
   xxx implements CallHeaderAuthenticator {
   @Override
       public AuthResult authenticate(CallHeaders incomingHeaders) {
       }
   }
   ```
   Then, `BasicCallHeaderAuthenticator` can decode username and password from 
`incomingHeaders`. I implements 
`BasicCallHeaderAuthenticator.CredentialValidator` and Override `AuthResult 
validate(String username, String password)` to complete authentication of 
username and password.
   ```
   xxx implements BasicCallHeaderAuthenticator.CredentialValidator {
   @Override
       public AuthResult validate(String username, String password) {
       }
   }
   ```
   
   But in my database(Apache Doris), the client's IP will also participate in 
authentication, so is there a way to get the ADBC client's IP in Flight Server?
   
   Thanks for your help.
