[StarCluster] Convert from python ssh to paramiko

[Orion Poplawski]

 From https://pypi.python.org/pypi/ssh/1.8.0:

This library originated as a fork of the Paramiko library, and has now been 
merged back into it. All fixes and features that were released or developed 
under the 'ssh' name have been incorporated into Paramiko! Please switch your 
dependencies to Paramiko 1.8.0 or newer.

Looks like StarCluster should switch to paramiko then.
