> marvin currently does all ssh connections using remoteSSHClient interface.
> There are several other methods that basically end up calling remoteSSHClient.
> Fabric on the other hand provides a more lucid and pythonic interface to deal
> with ssh-connections. Underneath fabric uses paramiko and provides several improvements
> 1. KeyPair support
> 2. Improved logging (current ssh logging is too verbose and hard to troubleshoot with)
> 3. parallel execution (useful for getting simulataneous LB connections going)
> In this work we need to deprecate marvin's remoteSSHClient from both the
> library and the tests and provide fabric interfaces to deal with cloudstack
> deployedVMs and hosts on the cloud infrasrtucture
