kubeadm: preflight check for incorrect FQDN

**What this PR does / why we need it**: There are a variety of system configuration errors (such as cloud-init bugs when deploying on AWS) which can cause hostname and uname -n to be wrong for a given host. This will cause kubeadm setup to fail in interesting and hard-to-figure-out ways (it doesn't fail until you start trying to set up DNS on the master, for example).

This PR adds a preflight check to test whether or not the server can reach itself using that name. This does not catch the case that the FQDN belongs to a different but valid server, but it would catch some of the cases. 

**Which issue this PR fixes** : fixes https://github.com/kubernetes/kubeadm/issues/135

Refactor the whole binary, a lot of changes in one commit I know, but I just hacked on this and modified everything I thought was messy or could be done better.
