Description

The current code requires closing the session separately from any "sub-interface" that use it - e.g.:

try (ClientSession session = ...obtain a session...;
      SftpClient sftp = ...obtain client(session)...) {
   ... use SFTP client ...
}

In some cases we may want to expose only the "sub-interface" and have it automatically close the underlying session when the "sub-interface" is closed. E.g.;

// The session is also closed when SFTP client is closed
try (SftpClient sftp = createSftpClient(...)) {
   ... use SFTP client ...
}

SftpClient createSftpClient(....) {
   ClientSession session = ...obtain a session...;
   SftpClient sftp = ...obtain client(session)...;
   return wrapAsCloseable(sftp, session);
}
