Fail fast if waiting for SSH to be available

[priyawadhwa]

Integration tests were running long because we'd wait up to 22 minutes for SSH to succeed while creating the host. This commit introduces a two minute timer on creating the host. On my Macbook Pro with the docker driver, creating the host takes 5 seconds, so 2 minutes should be more than enough time.

Should fix #6608
