ScpMover to transfer to a temporary file and rename after completion

[TAlonglong]

Feature Request

There could be an option using scp to transfer files to transfer the file to a temporary filename which get renamed upon completion.

Possible scenarios is when for some reason the transfer is interrupted for any reason you might get a valid filename with incomplete content.
Another is that you could think you have a complete file and start reading, when it's not complete.

So this is a bit more complex that I hoped for.
SCPClient only provides put https://github.com/jbardin/scp.py/blob/master/scp.py#L170-L171 , so the requested functionality needs to be implemented using exec_command https://github.com/paramiko/paramiko/blob/main/paramiko/client.py#L485-L492

so this can be something like this:

if transfere_temprary:
    ssh_tmp = ssh_connection.get_transport()
    ssh_tmp.exec_command("Copy from orig to remote tmp")
    if successful:
        ssh_tmp_exec_command("remote rename to remote orig")
