Fixes: #9684 Issue link: https://github.com/spring-projects/spring-integration/issues/9684 The `RemoteFileTemplate` is missing to create a temporary remote directory * Fix `RemoteFileTemplate.sendFileToRemoteDirectory()` to create a `temporaryRemoteDirectory` as well if it is different from already created `remoteDirectory` * Add `SftpServerOutboundTests.autoCreateTemporaryDirectory()` to verify that `temporaryRemoteDirectory` is created and in-use * Some other `SftpServerOutboundTests` refactoring for better code style **Auto-cherry-pick to `6.3.x`**
