AWS: Set OS defaults for kube 1.2

Browse Source 
Default distro is jessie, due to the support situation with Ubuntu
distros.  Default ubuntu distro is wily.

Update the docs to reflect the recommended distros with kube-up, and to
encourage contributions for other distros.

**KUBE_OS_DISTRIBUTION**
The distribution to use. Valid options: `trusty`, `vivid`, `coreos`, `wheezy`, `jessie`
The distribution to use. Defaults to `jessie`
Defaults to vivid (Ubuntu Vivid Vervet), which has a modern kernel and does not require updating or a reboot.
Supported options:
`coreos` is also a good option.
* `jessie`: Debian Jessie, running a custom kubernetes-optimized image. Should
be supported until 2018 by the debian-security team, and until 2020 by the
debian-LTS team.
* `wily`: Ubuntu Wily. Wily is not an LTS release, and OS support is due to
end in July 2016.
* `vivid`: Ubuntu Vivid. Vivid OS support ended in early February 2016.
Other options may require reboots, updates or configuration, and should be used only if you have a compelling
requirement to do so.
Given the support situation, we recommend using Debian Jessie. In Kubernetes
1.3 Ubuntu should have their next LTS release out, so we should be able to
recommend Ubuntu again at that time.
Using kube-up with other operating systems is neither supported nor
recommended. But we would welcome increased OS support for kube-up, so please
contribute!
