I appreciate that we want to fix the ssh client. I'm not certain that writing our own is the best >answer.

I was supposed to fix oslo.processutils.ssh with this class, but it may
be fixed without it, not big deal.



In his comments on your pull request, the paramiko author recommended looking at Fabric. I know that >Fabric has a long history in production. Does it provide the required features?


Fabric is too much for just command execution on remote server. Spur seems like
good choice for this.

But I still don't understand: why do we need oslo.processutils.execute? We can use subprocess module. Why do we need oslo.processutils.ssh_execute? We can use paramiko
instead.
