Unmet dependencies on cluster create

[Zebradil]

Got the following error while trying to create a new cluster:

stderr:Process exited with status 1002018/10/07 00:44:49 run failed
command:apt-get install -y docker-ce kubelet=1.9.6-00 kubeadm=1.9.6-00 kubectl=1.9.6-00 wireguard linux-headers-$(uname -r) linux-headers-virtual

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 kubelet : Depends: kubernetes-cni (= 0.6.0) but 0.6.0-02 is to be installed

As a workaround I explicitly added kubernetes-cni=0.6.0-00 into installation instruction:

However, it'd be better to avoid hardcoding versions in such way. I can send PR for this if you like.

@Zebradil I just merged #193 which should fix the issue. You can build from source if you need the fix now.

Cool stuff. Thanks!
