Feature Enhancement : Add prefix or suffix to file name while the file is getting streamed via SFTP

Enhancement

I wanted to give a temporary filename to the file placed in remote server while it was getting streamed. I did not have any other option except renaming the file before and after reading the file. It will be very helpful to have a built-in feature to temporary rename file while streaming it.

Code which I tried

     <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-sftp</artifactId>
            <version>5.1.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-core</artifactId>
            <version>5.0.6.RELEASE</version>
        </dependency>

Sftp.outboundGateway(sftpSessionFactory(), GET, "payload.remoteDirectory + payload.filename").options(STREAM)

Start with the SFTP outbound gateway configuration shown in the issue, especially the STREAM option and the spring-integration-sftp dependency. Determine where a configurable temporary prefix or suffix would apply while the remote file is streamed. Done means streaming can use the temporary name without requiring manual renames before and after the transfer.
