Critical Description
(debating whether to fix this in 0.8.0 with another RC or shrug and accept that it's an edge case and fix it in 0.8.1...)
With the whirr.template changes added in WHIRR-593, it's no longer possible to specify whirr.bootstrap-user=user:password (or whirr.template=loginUser=user:password, for that matter) to specify login creds for the bootstrap user. This is generally not a problem, since most providers will either use SSH keys or return a generated password, which jclouds picks up. But if for some reason your provider has hard-coded passwords on the images, you're kinda screwed here. The specific change that broke this is https://github.com/apache/whirr/commit/d7865344354b602ad59146afc6eadd7df4b7d344#L9L274.
