Add some kind of parallelssh-likely code for yosemite/linux

[mutterroland]

Would be nice to have an integrated script for running commands (like reboot) on known machines that our current script returned as being problematic.

I have been working on a piece of code to do so but I've got stuck at the point we have to provide our DUO for logging in.

I've asked Aki for help. It's nice to have it there as well so anybody can come with ideas.

For now we have the following:

import paramiko

ssh = paramiko.SSHClient()

passPhrase = raw_input("What's your passphrase for private key?") #asks to provide password for passphrase

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) 

privkey = paramiko.RSAKey.from_private_key_file('/home/rolandmutter/.ssh/id_rsa', password=passPhrase) #locates private key and unlocks it

ssh.connect('t-yosemite-r7-230.test.releng.mdc2.mozilla.com', username='root', pkey=privkey) #main fuction to connect to host , that is hardcoded for now for test purposes

#paramiko.util.log_to_file(os.path.expanduser('/home/rolandmutter/paramiko.log'), logging.DEBUG)

stdin, stdout, stderr = ssh.exec_command('ls') # command to execute, again, hardcoded

print stdout.readlines() # prints what is shown in the machine bash

ssh.close()` # closes connection

Hey,
This is definitely something that we can do and it's on my radar.
For the MVP (minimum viable product) this feature won't be a priority, but once I'm done with the code refactoring I'm planning to do something like this (and even more, automated yosemite reimage)

Will come back to this issue in the weeks to come.
If you continue working on the implementation for this feature, feel free to assign this issue to yourself and make it as a pull request when you feel that the implementation does what you expect it.
If you need help with it, make a separate branch, and push directly to it (not via a fork)

Automated yosemite reimages should be pretty easy as we are doing it via one command line.

This was half-way implemented.
Windows / Linux are being reboot via -rb and using iLO
OSX remains to be handles, currently I'm looking for options.
