issue: #31222
grpcclient's `call` func return a unrecoverable error, then the caller's
retry policy also breaks due to this unrecoverable error.
This PR introduce `retry.Handle`, the new func use `func() (bool,
error)` as input parameters, which return `shouldRetry` directly, to
avoid grpcclient return a unrecoverable error
