title: SpringIntegration Sftp Adapters back off mechanism on Incorrect Host Details
body: <p>currently my springboot code retries again and again to send files to incorrect host address (files are not being sftp'd &amp; Exceptions are being logged as expected). I want sftp adapters to try connecting to Host for twice if couldn't then it should stop trying. Is there any back off mechanism in general for sftp adapters.</p>
