   ### Describe the usage question you have. Please include as many useful details as  possible.
   
   
   Hi 
   
   Im using python ArrowFlight client & server.
   I noticed that the internal implementation of "do_get" and "get_schema" functions are not the same
   "do_get" calls the "check_flight_status" function, while "get_schema" calls the "check_status" function
   do_get: https://github.com/apache/arrow/blob/66cb7495d1a43f3539cf66f6d88bac40fb9d28d4/python/pyarrow/_flight.pyx#L1633
   get_schema: https://github.com/apache/arrow/blob/66cb7495d1a43f3539cf66f6d88bac40fb9d28d4/python/pyarrow/_flight.pyx#L1614
   
   this causes errors to behave differently - 
   while "do_get" throws internal Flight errors, "get_schema" only throws Arrow Errors and IOErrors.
   
   Is this intentional? 
   Im asking because I noticed that my server is unavailable, i get "FlightUnavailableError" when calling "do_get" but I get "OSError" when calling "get_schema" (with the message: "Flight returned unavailable error, with message: unavailable. Detail: Unavailable") and im unsure how to handle such error and how should I know to trigger a retry on OSError. Also, im not sure when does other ArrowExceptions are thrown from flight - is there a documentation for that?
   
   Thanks!

   It should be using `check_flight_status`, a PR would be welcome if this is still not fixed.
