Allow the ssh output to be streamed.
Let's try logging the ssh output.
Simplify the non blocking Popen.
Also use the non blocking Popen in scp calls.
Remove remaining stream ssh definitions.
Update to latest unstable bootstrap script
More explicit conditional.
Disable ssh output streaming to the console when running parallel deployments.
Fix `None` has no `len()`
Popen output should log as debug not warning
Error out if nothing was done, ie, wrong or erroneous arguments were passed.
In order not to have a machine running because we failed to get an IP, issue a shutdown for it.
