The current SCP and SSH tasks documentation does not show the supported SSH server for Windows

It would be better if there is a list of Supported SSH server for Windows since some SSH servers (that only works with SFTP) will not work well with Bamboo SCP and SSH tasks

It should state that Bamboo SSH task is sending command to the server instead of accessing the remote server interactively, eg:

ssh username@remotehost "ls -al"
