Reduce the time to wait for SSH to be available
Overview
When we create a machine we wait for SSH to be available (there are multiple implementations of provisioned so check the OS specific one) this tries 60 times where the best-case scenario is 3 minutes and worse case 9 minutes. This is still fairly long and we should see if we can reduce it just for SSH so that we can fail early if a machine can't be provisioned.
It might be ideal if we make sure configurable.
